A McKinney, Texas, martial arts instructor is facing two counts of sexual assault of a child.

KXAS reported that authorities first charged Timothy Vidal, 34, an instructor and co-owner of Tiger Rock Martial Arts, with one count on March 5. After turning himself in last week, the teacher was hit with a second count on Wednesday.

Vidal was first accused of assaulting a 16-year-old student. A second 16-year-old student came forward after hearing of the original case.

The second victim told an interviewer that Vidal kissed her on the lips in the summer of 2015 when she was 14, according to an arrest affidavit obtained by the station. From there, the girl, who also worked at Tiger Rock Martial Arts, claimed the 34-year-old raped her on four different occasions within the past six months: twice at a storage unit used by the school, once at his condo, and once in a hotel room.

According to The Dallas Morning News, the second victim said she didn’t report the incidents because she feared for her safety and didn’t think anyone would believe her. She pointed out that Vidal—a sixth-degree black belt—was intimidating.

Tiger Rock Martial Arts announced Vidal’s firing on Wednesday in a statement, which read in part:

We take this situation very seriously and are committed to providing a safe environment for all members. We have a NO TOLERANCE policy and took swift and immediate action upon learning of these allegations on Monday.

Vidal is married and a father. Bags and boxes full of his plaques and trophies seen piled up on the curb outside his home, and his wife is believed to have filed for divorce on Monday, according to the news station.

The 34-year-old is currently held in the Collin County Jail on $150,000 bond.
