A 29-year-old Canadian man was arrested at a high school wrestling tournament in Tumwater on Wednesday, accused of videotaping at least 15 boys as they showered in a locker room.

Wrestlers from around the state competed at the Tumwater Invitational Wrestling Tournament at Tumwater High School, south of Olympia, said Tumwater police Lt. Bruce Brenna.

An 18-year-old who wrestles for Mountlake Terrace High School finished his match and took a shower; as he was getting out of the shower, he noticed a man in the locker room who was hiding something in his lap, Brenna said. When the wrestler went to retrieve his towel near where the man was sitting, he saw the screen of a video camera. He used his cell phone to call his mother, who was in the stands, he said.

The wrestler’s mother alerted coaches with the Mountlake team, who detained the man until police arrived just after 2:15 p.m., Brenna said.

The man was probably videotaping for about 25 minutes, police said.

Officers reviewed the tape and “as near as we can tell,” 15 boys were captured on video, Brenna said. Police found driving directions to the school in the man’s car, which was parked in the school parking lot; they also found directions to another location, but so far, police aren’t sure where he was planning on going.

The man, a resident of Delta, B.C., was booked into the Thurston County Jail on suspicion of 15 counts of voyeurism and is being held on $37,500 bail, Brenna said. Officers have contacted U.S. Customs officials and hope to use that agency to get in touch with Canadian authorities, he said.

“Obviously, if he’s been traveling around, (the investigation) could be much more far-reaching,” Brenna said.
