McKinney Police Officer Eric Casebolt Resigns In Wake of Pool Video Eric Casebolt was originally put on administrative leave but has now resigned.

 -- The police officer who was videotaped slamming a teen girl to the ground and raising his gun towards others during a fight at a Texas pool has resigned, his attorney told ABC News -- actions the local police chief described as "indefensible."

Cpl. Eric Casebolt's resignation comes a day after hundreds of protesters marched near the pool in McKinney where the incident took place last weekend.

McKinney Chief of Police Greg Conley said this evening that Casebolt's actions on the cell phone recording of the incident were "indefensible."

"Our policies, our training, our practice do not support his actions," he added.

Conley described Casebolt as being "out of control," while praising the actions of the 11 other officers on the scene.

"I had 12 officers on the scene and 11 of them... did an incredible job," Conley said.

Conley confirmed that there had been some other complaints against Casebolt, but Conley could not go into specifics.

The case against one of those who was arrested was dropped. It was not clear which case he was referring to.

The release of the video prompted national outcry after there were allegations that race played a factor in the way that the white officer treated the African-American teens.

But the McKinney Fraternal Order of Police vehemently denied that the incident was racially motivated.

"The McKinney FOP assures that this was not a racially motivated incident and can say without a shadow of doubt that all members of the McKinney FOP and McKinney PD do not conduct racially biased policing," lodge president Daniel Malenfant said in a statement.

The 41-year-old officer was put on administrative leave this past weekend.
