The Nigerian man charged with attempting to blow up a U.S. airliner on Christmas Day is scheduled to appear in a Michigan court Monday. On Sunday, authorities moved Umar Farouk Abdulmutallab, 23, to a federal prison from a hospital where he was treated for burns. Abdulmutallab says he was trained by al-Qaida operatives in Yemen. He allegedly tried to ignite explosives just before Northwest Airlines Flight 253 landed in Detroit on a trip from Amsterdam. The device failed to explode and Abdulmutallab burned his leg before other passengers and flight crew restrained him. Abdulmutallab's family released a statement Monday saying they lost contact with him while he was studying abroad. Umaru Mutallab, a renowned former banker and government minister, warned Nigerian security agencies about his son's views two months ago. The suspect is listed in a U.S. government intelligence database, but he was not on the so-called "no-fly list." Officials are reviewing security and trying to determine how Abdulmutallab boarded a U.S.-bound plane with potential explosives. Homeland Security Secretary Janet Napolitano told CNN there is "no indication" that Friday's attempted attack was part of a larger terrorist plot. U.S. and European airlines have tightened security since the incident. Republican Congressman Peter King, of the House Homeland Security Committee, said Sunday the U.S. security system failed and the suspect may have been seconds away from killing hundreds. White House Press Secretary Robert Gibbs told ABC News the incident has prompted officials to review procedures for placing potential terrorists on watch lists, and re-evaluate security systems at airports. Officials say Abdulmutallab began his trip in Nigeria. The Nigerian government says the suspect had been living outside the country for some time. Nigeria's information minister told reporters Sunday that Abdulmutallab snuck into the country Thursday, the day before the attack, and left the same day. Nigerian officials say they have launched their own probe into the incident. Some information for this report was provided by AP, AFP and Reuters. .
