The lights were on and the club was slowly emptying out, but NFL star Adrian Peterson was getting arrested ... as you can see in new video obtained by TMZ.
As TMZ first reported, Adrian was quite drunk at the time of his arrest Saturday morning, which police say came after Peterson shoved an off-duty police officer who was working security at the club.
In the video, Peterson can be seen being escorted out by cops while several people look on. The woman who shot the video tells TMZ she didn't see what lead to the arrest, but once it was going down ... she felt the cops were being super aggressive with him.
Peterson was eventually charged with resisting arrest and posted bail a short time later.
