San Francisco 49ers linebacker Aldon Smith was detained by police Sunday at Los Angles International Airport, allegedly for being uncooperative with security and yelling that he had a bomb.

Although a A Los Angeles Police Department spokesperson would not confirm Smith was involved, 49ers General Manager Trent Baalke said in a statement released by the team: “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.”

According to LAPD public information officer Karla Ortiz, a San Jose man was taken to booking and his identity was to be released after that was completed.

“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,” 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.”

Smith, who turns 25 in September, was led away from the Southwest Airlines gate, in full view of passengers — and passengers armed with cellphones. TMZ has video that is purported to be of the incident here.

“I heard him say, ‘I did nothing wrong,'” John Egan, a San Antonio man, told MercuryNews.com. “The whole thing ratcheted up from there. The cops were trying to calm him down. He wasn’t out of control, just agitated.”

Smith has had a number of issues involving police since he arrived in San Francisco in 2011. Last fall, he was arrested on suspicion of driving under the influence after a single-car accident, then took a five-week leave of absence to undergo treatment at a rehab facility. After being stabbed at a party last June, he is facing three felony counts of possessing illegal assault rifles. He was arrested in Miami in January 2012 on suspicion of drunken driving and was charged with reckless driving.

This has been an embarrassing offseason for the 49ers. Last week, Miami police said that quarterback Colin Kaepernick and wide receiver Quinton Patton are part of an investigation involving a “suspicious incident.” Kaepernick tweeted last week that the allegations are not true. On Friday, cornerback Chris Culliver was arraigned on two counts of misdemeanor hit-and-run and one count felony possession of metal knuckles after knocking over a bicyclist with his car last month. He has entered not-guilty plea. In January, center Daniel Kilgore was arrested for public intoxication in Tennessee.
