Umar Farouk Abdulmutallab

Umar Farouk Abdulmutallab (Arabic: عمر فاروق عبد المطلب ; also known as Umar Abdul Mutallab and Omar Farooq al-Nigeri; born December 22, 1986) popularly referred to as the "Underwear Bomber", is a Nigerian man who, at the age of 23, confessed to and was convicted of attempting to detonate plastic explosives hidden in his underwear while on board Northwest Airlines Flight 253, en route from Amsterdam to Detroit, Michigan, on Christmas Day, 2009.

Al-Qaeda in the Arabian Peninsula (AQAP) claimed to have organised the attack with Abdulmutallab; they said they supplied him with the bomb and trained him. Connections to Al-Qaeda and Anwar al-Awlaki have been found, although the latter denied ordering the man to do the bombing.

Abdulmutallab was convicted in a U.S. federal court of eight criminal counts, including attempted use of a weapon of mass destruction and attempted murder of 289 people. On February 16, 2012, he was sentenced to 4 life terms plus 50 years without parole. He is currently incarcerated at ADX Florence, the supermax federal prison in Colorado.
