A police officer in Texas has been taken off duty after a video showed him pointing a gun at a group of teenagers.

The video, filmed in the town of McKinney on Friday night, showed officer Corporal David Eric Casebolt pinning a black 15-year-old girl in a bikini to the ground with his knees.

Hundreds of people have since marched through McKinney demanding that the police officer, who is white, should be dismissed.

Connie Rice, a member of President Obama's Task Force on 21st Century Policing, said the officer was "totally out of control".

"If you're a cop you never un-holster your gun unless you intend to kill somebody. He took his gun out to intimidate these children... there's no way he can justify what he did," she said.

Police said the video "raised concerns that are being investigated". Mr Casebolt has been placed on leave and has not commented on the investigation.
