Minneapolis police say they are looking into a video that appears to show two uniformed Minneapolis police officers standing by as a bouncer repeatedly punches a handcuffed man lying facedown outside a downtown strip club.

A bystander made a cellphone video of part of the incident, which is said to have occurred Saturday night outside Augie’s Cabaret and posted it to social media on Sunday. By Tuesday morning, it had been viewed more than 16,000 times on Facebook and shared hundreds of times.

The 10-second video shows a man on the ground with his arms cuffed behind his back as a bouncer punches him three times before being pulled away by someone in the crowd. A police report said the incident occurred at 2:17 a.m., and that David S. Mitchell, 28, of Burnsville was cited for 5th-degree assault “after officers witnessed him assault a security [sic] at that location.”
