This has always been illegal but post 9/11 there’s certain things you just DON’T do in an airport and yelling “bomb” is one of them.

According to TMZ Sports San Francisco 49ers superstar Aldon Smith was just arrested at LAX after allegedly yelling “bomb” in the airport terminal.

Law enforcement says the drama began at the security gate when he was randomly selected for a secondary screening.

Cops say Smith 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 toward the gate area.”

In the video Smith is in handcuffs and telling the police he didn’t do anything wrong.  The cop keeps repeating “you’re buggin bro”.  Smith says they’re going to be “embarrassed”.

Cops say Smith was uncooperative during the arrest. He was eventually transported to a nearby LAPD station to be booked.

Smith has a long history with the law — the 24-year-old defensive end was arrested in 2012 for DUI and in 2013, he was charged with 3 counts of illegal possession of an assault weapon stemming from a violent incident at his home in San Joe, Ca where Smith was stabbed.



He posted $20,000 bail Sunday night…
