Prosecutors say an Orange County coach has been charged with the sexual abuse of seven girls in a water polo club that practices in Los Alamitos.

The Orange County District Attorney’s office announced Wednesday that Irvine resident Bahram Hojreh, 42, faces charges including sexual battery and sexual penetration by foreign object of a minor. It wasn’t immediately known if Hojreh has an attorney.

Hojreh was suspected of sexually assaulting seven water polo players, four of whom were 15 or younger, between September 2014 and January, according to a statement from the Orange County District Attorney’s Office. He was working as a water polo coach at the International Water Polo Club in Los Alamitos at the time of the alleged crimes and the crimes reportedly took place during one-on-one coaching sessions, the DA’s Office said.

The charges include 4 felony counts of lewd acts on a child, 4 counts of sexual penetration of a minor with a foreign object, a lewd act on a child under 14, 7 misdemeanor counts of child annoyance and 6 misdemeanor counts of sexual battery.

Two of the girls reported the alleged assaults to their parents, who contacted Child Protective Services. The Los Angeles Police Department has identified five more victims, according to the DA’s office.

The charges come months after his group, the International Water Polo Club, was removed from using the pool at a military base. Police informed base officials they were investigating allegations involving sexual misconduct against the program’s director.

Hojreh touts himself as a coach for nearly a quarter-century who has “helped develop multiple Olympians.” He serves on the board for a local chapter of USA Water Polo, the sport’s governing body in the United States.

Hojreh is next due in court in Westminster on June 14. Police believe there may be other victims. Anyone with more information is asked to call LAPD Detective Delana Lopez at 562-431-2255, ext. 407.
