A karate instructor is facing a sexual assault of a child charge after he allegedly raped a boy at a karate camp in Texas, per an arrest affidavit obtained by PEOPLE.

William Propper, 30, allegedly sexually assaulted the boy at the Safety America Karate school in Sugar Land, according to the affidavit.

The victim was 13 or 14 at the time of the alleged assault in 2022 or 2023, according to the affidavit.

A detective with the Sugar Land Police Department was assigned the case on Jan. 31, after the boy’s mother contacted police about the alleged sexual assault. The boy’s mother allegedly told police that her son “disclosed to her” that Propper had raped her son in a staff bathroom at the karate school, per the affidavit.

The boy told a trained forensic interviewer that Propper had been his karate instructor since 2018.

"John Doe explained that it occurred while he was attending the Safety Karate school in Sugar Land during the summer for a summer camp," according to the affidavit. "John Doe explained that suspect “offered to ‘try out sex’ and suspect told him that [victim] was mature enough now to have sex."

After the alleged rape, Propper “told him to keep what happened in the bathroom a secret,” according to the affidavit.
