The NYPD says it is conducting a brutality probe against four officers after a video showed a suspect being struck and kicked.
The officers were placed on modified duty after the footage surfaced last weekend on the Internet, reports The New York Post.
Police spokesman Paul Browne says the officers' guns and shields have been removed during the investigation.
The video shows 19-year-old Jatiek Reed appearing to resist arrest by throwing a couple of kicks and swats.
Then it shows Reed being struck with police batons and kicked. One officer holds him down.
Police Commissioner Ray Kelly called the video "troubling" at a news conference Wednesday.
Reed's mother told the Post that her son required staples in his head and arm.
Reed was arrested on assault charges. Information on his attorney was not available.
