San Francisco 49ers linebacker Aldon Smith was detained at LAX on Sunday afternoon after refusing to cooperate with security and reportedly claiming he had a bomb on him.

“At approximately 1400 hrs, a 25-year-old male resident of San Jose, California, was going through Terminal 1 screening and was randomly selected for a secondary screening,” Sgt. Karla Ortiz said in a statement. “The suspect then became belligerent and uncooperative with the process and with the TSA agent, making a comment indicating that he was in possession of a bomb before proceeding towards the gate area.

“Los Angeles Airport Police made contact with him at the gate and he was positively identified as the person in question. Once again the male subject became uncooperative and he was detained and taken into custody by Airport Police and is currently being transported to LAPD for booking.”

This latest incident just adds to the list of questionable behavior of the star NFL player. Smith spent five weeks at a substance-abuse treatment facility last fall following an arrest for suspicion of DUI and is also currently facing three felony counts of possessing illegal assault rifles, which were found after Smith was stabbed at his house party in 2012.
