A McKinney, Texas, Police Corporal has resigned after video showed him pushing a 15-year-old girl in a swimsuit to the ground and drawing his service weapon on other teens, reports KDFW.

McKinney Police Chief Greg Conley said the corporal's actions were "indefensible" during a Tuesday evening news conference.

"He came into the call out of control and as the video shows was out of control during the incident." Conley said. "I had 12 officers on the scene and 11 of them performed according to their training."

The video of the Friday incident involving the corporal at a McKinney neighborhood pool went viral and had initially landed him on administrative leave while police officials conduct an investigation.

The corporal was seen pulling Dajerria Becton to the ground and pinning her with his knees while she cried out. He also pulled out his gun and pointed it at other teens and briefly ran after them before being stopped by two fellow McKinney police officers. Throughout the video the corporal is heard repeatedly cursing.

"Our policies, our training, our practice do not support his actions," Conley said.
