Officers were called to the a local community pool around 7:15 p.m. local time to respond to a "disturbance involving multiple juveniles at the location, who do not live in the area or have permission to be there, refusing to leave," the McKinney Police Department said in a post on its Facebook page. Other calls also advised that the teens were "actively fighting," police said.

"First responding officers encountered a large crowd that refused to comply with police commands. Nine additional units responded to the scene. Officers were eventually able to gain control of the situation," police said.

However, video later emerged of one officer aggressively handcuffing and detaining teens who described themselves as bystanders, before wrestling a girl in a bathing suit to the ground and drawing his weapon on others who came to her aid.
