(WXYZ) - When Umar Farouk Abdulmutallab tried to take down Northwest Flight 253 on Christmas Day 2009 using a chemical bomb in his underwear, officials scrambled to figure out how he smuggled the device on the plane.
Now security officials have a new concern – body bombs. According to ABC News sources the leader of Al-Qaeda in Yemen is so bent on bringing down another jetliner he is experimenting with implanting explosives inside suicide bombers' bodies.
Experts tell ABC News the non-metal bombs can be placed inside the stomach area. But a local retired FBI agent tells 7 Action News that operatives are still trying to determine how to detonate the bombs once they are inserted inside someone's body.
Right now there is no specific threat, but because Tuesday is the anniversary of Osama Bin Laden's death officials are taking any general threats very seriously.
Metro Airport's TSA spokesman says the body scanners at Metro are equipped to detect metal and non-metal objects, but the TSA would not further elaborate on the technology used.
