Video posted over the weekend appears to show a group of NYPD officers arresting a young man in a Flatbush Target, punching him as they try to subdue him.
The incident occurred at the Target store on Flatbush and Nostrand avenues at around 8 p.m. Saturday.
The video begins with the suspect already on the floor being punched. A worker from a nearby store claims the suspect may have hit an officer while being arrested, but authorities have not commented on what led to the incident.
