Source: Terror suspect's father tried to warn authorities 27 Dec 2009 The father of a man suspected in a botched terror attack aboard a Northwest Airlines flight contacted the U.S. Embassy in Nigeria recently with concerns his son was planning something, a senior U.S. administration official said Saturday. The father -- identified by a family source as Umaru Abdul Mutallab -- contacted the U.S. Embassy "a few weeks ago" saying his son, Umar Farouk Abdulmutallab, had "become radicalized," the senior administration official, who is familiar with the case, told CNN. Abdulmutallab, 23, was charged in a federal criminal complaint Saturday with attempting to destroy the plane Friday on its final approach to Michigan's Detroit Metropolitan Airport, and placing a destructive device on the aircraft, the Department of Justice said.
