The Philadelphia Police Department has opened an internal affairs investigation into an April arrest after a video surfaced showing what appeared to be officers repeatedly punching and kicking a suspect.

The department announced the review of the April 3 arrest on Thursday, the day the video appeared on YouTube.

An officer is heard saying, "Here comes the Taser," but police say there's no indication one was used on 22-year-old Tyree Carroll.

Police say Carroll fought with officers when they stopped him for a drug violation and bit two of them.

Carroll is charged with drug possession, assault and resisting arrest. Police say he had less than a quarter of an ounce of crack on him.

His lawyer's voicemail box was full. The lawyer did not respond to a faxed message.
