Why was he ever allowed to fly? Syringe bomber had been barred from Britain, was on a terror list and even his father had warned U.S.

The former London student charged with attempting to blow up a transatlantic airliner carrying 278 passengers was barred from Britain, it was revealed. Umar Farouk Abdulmutallab finished an engineering course at the University College London last year, but a fresh visa request was refused in May after he applied for a bogus course, Whitehall sources said.

The 23-year-old son of a wealthy Nigerian banker was charged in hospital last night with attempting to destroy the aircraft during its final approach to Detroit airport on Christmas Day, the US Justice Department said. Four weeks ago Abdulmutallab's father told the U.S. embassy in Abuja, Nigeria, that he was concerned about his son's religious beliefs. This information was passed on to U.S. intelligence officials.

The alleged bomber was also on a separate U.S. terror database, but was not considered an immediate threat. His name was absent from 'no-fly' lists. Abdulmutallab, who had previously been living in a luxury mansion block while studying at University College London, was also charged with with placing a destructive device on the Northwest Airlines Flight 253. According to an affidavit filed in support of the criminal complaint, Abdulmutallab had a device attached to his body when he boarded the aircraft in Amsterdam on Christmas Eve. (Daily Mail)
