Man with bomb-making supplies arrested at Oakland Airport 16 Nov 2012 Officials are investigating a Southern California man who was arrested at Oakland International Airport Thursday night after he was found with materials that could be used to make a bomb. It happened around 8 p.m. Thursday. The man, who had a Southern California address, was trying to board a Southwest Airlines flight to Los Angeles. He was going through a security checkpoint when TSA inspectors noticed suspicious items in the bin where he had placed his carry-on bag. They found what appeared, to them, to be components of an Improvised Explosive Device (IED) including a watch with wires, fuses, and a toggle switch. All the components were there except for an explosive.
