Police in Cambridge, Massachusetts, arrested Laquan Holland, 40, after he was accused of sexually assaulting multiple people in a Planet Fitness women's locker room, Boston 25 News reported.

There is no evidence suggesting that Holland identified as transgender at any point of his life. But Rowling says pro-trans policies that let anyone use the changing room that aligns with their self-declared gender identity are being exploited by predators like Holland.
