McKINNEY, Texas (AP) — The chief of police in McKinney, Texas, says the actions of an officer at a pool party in the Dallas suburb were “indefensible.”

McKinney Police Chief Greg Conley made the comments during a news conference today after Officer David Eric Casebolt resigned.

A viral video showed Casebolt pushing a bikini-clad girl to the ground on Friday and brandishing his gun at other black teens after he and other officers responded to complaints about the pool party at a community-owned McKinney swimming pool.

Conley had placed the 41-year-old former Texas state trooper on administrative leave after the incident. Conley said Casebolt resigned while under investigation.
