McKINNEY, Texas — A suburban Dallas police officer has been placed on administrative leave after a video showed him pushing a 14-year-old girl in a swimsuit to the ground outside a pool and pointing his gun at other teens.

McKinney Police Chief Greg Conley said at a news conference Sunday that the incident began when officers responded Friday to a report of a disturbance involving a group of juveniles at a neighborhood pool.

The police department said in an earlier statement that the young people did not live in the area or have permission to be there.

When officers arrived, residents and private security pointed out the juveniles, who were “creating the disturbance, fighting and refusing to leave,” Conley said.

As officers dispersed the crowd, the 14-year-old girl was “temporarily detained” by an officer, said Conley, who did not describe what led to her detainment.
