A Planet Fitness member in North Carolina allegedly entered a ladies’ locker room at the gym and stripped down “completely naked,” claiming that he identified as a woman, according to police and 911 callers.

Christopher Miller, 38, was arrested on a charge of indecent exposure and booked into the Gaston County jail last Thursday, with his online inmate entry identifying him as a male. His mugshot showed the suspect sporting a light-colored beard and mustache.

Miller’s arrest on a felony charge came after an alarmed woman at the Gastonia Planet Fitness called 911 to report there was a naked man in the ladies’ locker room, reported WSOC-TV.

“It’s a man but he says he identifies as a woman, and he won’t leave the restroom,” the 911 caller told an emergency dispatcher. “But he is just walking around showing us his — and he won’t leave.” “OK, so he is completely naked?” the dispatcher asked.

“He is completely naked,” the caller said. Sources told the outlet that Miller allegedly asked a female gym member in the locker room to lotion him up and take a shower together.

Planet Fitness allows members to use the restroom and locker room consistent with their self-reported gender identity, but there was no indication that Miller had identified himself as a transgender woman before venturing inside the ladies’ locker room.
