ALAMEDA, Calif. (AP) — A high school water polo player in the Bay Area has been accused of sexually assaulting an opposing player during a game.

The Alameda Police Department says they have opened a criminal investigation after multiple Encinal High School players accused a Berkeley High School team member of behaving inappropriately in the water during an Oct. 11 game.

Berkeley Unified School District spokesman Charles Burress declined to comment on the investigation.

This is the second time in less than a year that a Bay Area high school water polo game has led to a criminal investigation. Last year, a boy playing for Acalanes High in Lafayette broke the nose of an opponent during a game and was charged with felony assault and battery.
