(CNN) - An AWOL Muslim American Army private arrested near Fort Hood, Texas, told investigators that he wanted to attack fellow soldiers outside Fort Hood, two law enforcement officials said Thursday.

FBI agents discovered a bevy of potential bomb-making materials in the hotel room of Pfc. Naser Jason Abdo, who refused to deploy to Afghanistan and later went AWOL from Fort Campbell in Kentucky after being charged with possessing child pornography, said FBI spokesman Erik Vasys.

After a tip-off from a local gun shop, Killeen police arrested Abdo in a traffic stop Wednesday, Vasys said.
