Antonio Brown Runs Through Crowd With What Looks Like Gun, on Video

Antonio Brown seems to have had a weapon in his hands at some point during his tense altercation with alleged robbers last night — right before gunshots cut through the night air.

The former professional NFL player was caught on camera after leaving Adin Ross‘ Brand Risk kickboxing event Friday night … appearing to hold a piece in his left hand.

At first, he’s walking alongside a pal — before he starts running through the crowd, turns a corner out and raises his arm.

We first shared exclusive video of Brown getting into a brawl with a bunch of dudes after the event — throwing haymakers before some big men got in the middle and broke it up.

Brown was handcuffed at the scene, but ultimately wasn’t arrested … and, he later took to social media to claim these dudes tried to jump him — and, he’s considering pressing charges against them.

Worth noting … several people hanging around Brown during the incident say Brown had a gun and fired the shots — but, AB hasn’t said anything about using his weapon.
