A Gainesville man impersonated a law enforcement officer before he sexually assaulted a woman, police said.

Dionicio Perez, 30, is charged with rape, first-degree burglary and impersonating a police officer, the Gainesville Times reported. The incident happened Jan. 31 at the Motel 6 on Monroe Drive, Gainesville police Sgt. Kevin Holbrook told the Times.
