For the 2004–5 academic year, Abdulmutallab studied at the Sana'a Institute for the Arabic Language in Sana'a, Yemen, and attended lectures at Iman University.
He was president of the school's Islamic Society, which some sources have described as a vehicle for peaceful protest against the actions of the United States and the United Kingdom in the War on Terrorism. During his tenure as president, along with political discussions, the club participated in activities such as martial arts training and paintballing; at least one of the Society's paintballing trips involved a preacher who reportedly said: "Dying while fighting jihad is one of the surest ways to paradise." He was well liked as president of the society and considered to be moderate though politically engaged. He organized a talk about the detention of terror suspects, and walked down Gower Street in an orange jumpsuit.
He organized a conference in January 2007 under the banner "War on Terror Week", and advertised speakers including political figures, human rights lawyers, speakers from Cageprisoners, and former Guantánamo Bay detainees. One lecture, Jihad v Terrorism, was billed as "a lecture on the Islamic position with respect to jihad".
At the age of 21, Abdulmutallab told his parents that he wanted to get married; they refused on the grounds that he had not yet earned a master's degree.
In May 2009, Abdulmutallab tried to return to Britain, ostensibly for a six-month "life coaching" program at what the British authorities concluded was a fictitious school; the United Kingdom Border Agency denied his visa application. His name was placed on a UK Home Office security watch list which, according to BBC News, meant that he could not enter the UK. Passing through the country in transit was permissible and he was not permanently banned; the UK did not share the information with other countries. This status was based on his visa application being rejected to prevent immigration fraud rather than for a national security purpose.
His family became concerned in August 2009 when he called to say he had dropped the course, but was remaining in Yemen. By September, he routinely skipped his classes at the Institute and attended lectures at Iman University, known for suspected links to terrorism. "He told me his greatest wish was for sharia and Islam to be the rule of law across the world," said one of his classmates at the institute. The Institute obtained an exit visa for him at his request, and on September 21 arranged for him to go the airport to return home. However, he did not leave the country at that time.
In October 2009, Abdulmutallab sent his father a text message saying that he was no longer interested in pursuing an MBA in Dubai, and wanted to study sharia and Arabic in a seven-year course in Yemen. When his father threatened to cut off his funding, Abdulmutallab said he was "already getting everything for free" and refused to tell his father who would support him. He sent more texts stating he would be cutting off contact and disowning his family. The family last had contact with Abdulmutallab in October 2009.
Yemeni officials said that Abdulmutallab was in Yemen from early August 2009, and overstayed his student visa (which was valid through September 21). He left Yemen on 7 December, flying to Ethiopia, and then two days later to Ghana. Yemeni officials have said that Abdulmutallab travelled to the mountainous Shabwah Province to meet with "al-Qaeda elements" before leaving Yemen. A video of Abdulmutallab and others training in a desert camp, firing weapons at targets including the Star of David, the British Union Jack flag, and the letters "UN", was produced by al-Qaeda in Yemen. The tape includes a statement justifying his actions against "the Jews and the Christians and their agents." Ghanaian officials say he was there from December 9 until December 24, when he flew to Lagos.
In February 2010, a Yemeni security official said that 43 people were being interrogated for links to the Christmas Day attempt, including foreigners, some of them studying Arabic and others married to Yemeni women. Abdulmutallab was thought to have used Arabic studies as a pretext for entering the country. Saïd Kouachi, one of the attackers—now deceased—in the Charlie Hebdo shooting, is believed to have been one of Abdulmutallab's neighbors at the Yemeni Arabic language school.
On 11 November 2009, British intelligence officials sent the US a cable indicating that a man named "Umar Farouk" had spoken to al-Awlaki, pledging to support jihad, but the cable did not give Abdulmutallab's last name.[dead link] On 19 November, Abdulmutallab's father consulted with two CIA officers at the US Embassy in Abuja, Nigeria, reporting his son's "extreme religious views", and told the embassy that Abdulmutallab might be in Yemen. Acting on the report, the CIA added the suspect's name in November 2009 to the US's 550,000-name Terrorist Identities Datamart Environment, a database of the National Counterterrorism Center (NCTC). It was not added to the FBI's 400,000-name Terrorist Screening Database, the terror watch list that feeds both the 14,000-name Secondary Screening Selectee list and the US's 4,000-name No Fly List, nor was Abdulmutallab's American visa revoked.
Abdulmutallab's name had come to the attention of intelligence officials many months before that, but no "derogatory information" was recorded about him. A Congressional official said that Abdulmutallab's name appeared in US reports reflecting that he had connections to both al-Qaeda and Yemen. The NCTC did not check to see whether Abdulmutallab's American visa was valid, or whether he had a British visa that was valid; they did not learn that the British had rejected Abdulmutallab's visa application earlier in 2009. British officials had not informed the United States because the visa application was not denied for a national security purpose.
He also described jihadist fantasies about Muslims engaging in a worldwide jihad and establishing a Muslim empire.
In April 2009, Abdulmutallab had applied to attend an Islamic seminar in Houston, Texas. He obtained a multiple-entry visa in the U.S. Consulate in June 2008 that would be valid until June 2010. He attended the Islamic seminar from 1–17 August at AlMaghrib Institute. When Abdulmutallab returned to Yemen later in 2009, purportedly to study Arabic again, he appeared to have undergone a personality change: he was more religious and "a loner", and wore traditional Islamic clothing. He rarely attended class, and sometimes he left class midway to go pray at a mosque.
A number of sources reported contacts between Abdulmutallab and Anwar al-Awlaki, an American Yemeni Muslim lecturer and spiritual leader who had been accused of being a senior al-Qaeda talent recruiter and motivator. Al-Awlaki, who was killed by an unmanned United States drone in Yemen in September 2011, was previously an imam in the U.S. He was associated with three of the 9/11 hijackers, who prayed at his mosque; the 2005 London Bombings; a 2006 Toronto terror cell; a 2007 Fort Dix attack plot; and the 2009 Fort Hood shooter.
Despite being banned from entering the UK in 2006, al-Awlaki spoke via video-link in 2007–09 on at least seven occasions at five different venues in Britain. During this period he gave a number of video-link lectures at the East London Mosque before being banned by the mosque in 2009.
Intelligence officials suspect al-Awlaki may have directed Abdulmutallab to Yemen for al-Qaeda training. One government source described intercepted "voice-to-voice communication" between the two during the autumn of 2009. After being arrested, Abdulmutallab reportedly told the FBI that al-Awlaki was one of his trainers when he did al-Qaeda training in remote camps in Yemen. There were "informed reports" that Abdulmutallab met al-Awlaki during his final weeks of training and indoctrination prior to the attack.
A U.S. intelligence official said that information pointed to connections between the two:
Yemen's Deputy Prime Minister for Defence and Security Affairs, Rashad Mohammed al-Alimi, said Yemeni investigators believe the suspect travelled in October to Shabwa, where he met with suspected al-Qaeda members. They met in a house built and used by al-Awlaki to hold theological sessions, and Abdulmutallab was trained and equipped there with his explosives.
Abdulmutallab spent about 20 minutes in the toilet as the flight approached Detroit, then covered himself with a blanket after returning to his seat. Other passengers heard popping noises and smelled a foul odour. Some saw flames on Abdulmutallab's trouser leg and the wall of the plane. Jasper Schuringa, a Dutch film director, held Abdulmutallab down while flight attendants extinguished the flames. Abdulmutallab was taken toward the front of the aircraft cabin, where he told a flight attendant he had an explosive device in his pocket. The device was a six-inch (15 cm) packet containing the explosive powder PETN, sewn into his underwear.
Two days after the attack, Abdulmutallab was released from a hospital where he had been treated for first and second degree burns to his hands, and second degree burns to his right inner thigh and genitalia, sustained during the attempted bombing. He was subsequently held at the Federal Correctional Institution, Milan, a federal prison in Michigan, where he remained during court proceedings.
New restrictions were imposed on U.S. travelers, but the government did not publicise many of them because security officials reportedly "wanted the security experience to be 'unpredictable'". One day after she said that the system had "worked", Secretary of Homeland Security Janet Napolitano acknowledged that the aviation security system had indeed failed.
On 27 January 2010, the House Committee on Homeland Security continued a series of hearings across Capitol Hill that started prior to 27 January 2010, all looking into the events leading up to and after the attempted bombing of Flight 253 over Detroit. Patrick F. Kennedy, an undersecretary for management at the US State Department, said Abdulmutallab's visa was not taken away because intelligence officials asked his agency not to deny a visa to the suspected terrorist over concerns that a denial would have foiled a larger investigation into al-Qaeda threats against the United States.
Several Muslim organisations and leaders in both the United States and the United Kingdom condemned the terrorist and extremist actions of Abdulmutallab as contrary to Islamic beliefs. Concerns in the media also arose that Nigerians would now be "unduly stigmatized" due to the incident.
Abdulmutallab was questioned by the authorities for several hours before being given medical treatment for his injuries.
Abdulmutallab initially cooperated with investigators, then stopped talking. The decision to read him his Miranda rights, advising him of his right to remain silent, generated criticism from a number of mostly Republican politicians. After the FBI brought two of Abdulmutallab's relatives from Nigeria to the U.S. to speak with him, he once again began to cooperate.
On 14 September 2010, the Associated Press reported Abdulmutallab had dismissed his court-appointed defence team to defend himself. The court subsequently appointed Anthony Chambers to act as standby counsel. On 12 October 2011, Abdulmutallab, against the advice of Chambers, pleaded guilty to the eight charges against him, including the attempted use of a weapon of mass destruction and the attempted murder of the 289 people on the plane. Both charges carried a potential death sentence. He reportedly changed his mind about his plea after the prosecution completed its opening arguments.
Sentencing was initially scheduled for 12 January 2012, but was subsequently postponed to 16 February 2012, to give Abdulmutallab more time to review the presentence investigation report completed by the United States Probation Service. On 13 February 2012, Chambers filed a motion arguing that sentencing his client to life in prison would constitute cruel and unusual punishment under the Eighth Amendment to the United States Constitution because no one other than his client suffered physical harm during the attempted attack. The motion was rejected, and on 16 February 2012, Judge Nancy Edmunds of Federal District Court in Detroit sentenced Abdulmutallab to life in prison. In a statement after the sentencing, Abdulmutallab's family said, "We are grateful to God that the unfortunate incident of that date did not result in any injury or death".
