LOS ANGELES — San Francisco 49ers linebacker Aldon Smith was arrested at Los Angeles International Airport on Sunday after he allegedly became argumentative with a screening agent and made comments suggesting he had a bomb, police said.

Smith, 24, was booked on suspicion of making a false report of a bomb threat.

Smith was randomly selected for a secondary screening when he “became belligerent and uncooperative with the process,” said airport police Sgt. Karla Ortiz.

Smith then made a comment to a Transportation Security Administration agent “indicating he was in possession of a bomb before proceeding towards the gate area,” Ortiz said.

Airport police later caught up with Smith at the gate, where he allegedly became uncooperative with police and was then detained.

In a statement, 49ers general manager Trent Baalke said, “We are disappointed to learn of the incident today involving Aldon Smith. As this is a pending legal matter and we are still gathering the pertinent facts, we will have no further comment.
