Texas pool party policeman quits

A US police officer filmed wrestling a black girl to the ground and pointing his gun at teenagers in Texas has quit his job.

In a video - filmed on Friday in McKinney - Corporal (Cpl) Casebolt, who is white, is seen pinning 15-year-old Dajerria Becton to the ground with his knees.

Police said he was responding to reports of disturbances at a pool party.

Hundreds of people later protested at the scene, demanding that the corporal be fired from his job.

The issue of how black people are treated in the United States has been big news over the last year.

Protests claiming black people aren't treated as fairly as white people have sprung up across the US.

Protests have followed the deaths of several African Americans in police incidents since July 2014 - Michael Brown in Ferguson, Missouri, Eric Garner in New York, Freddie Gray in Baltimore and Tamir Rice in Cleveland, Ohio.
