A young woman says she was sexually assaulted along an eastern Kansas highway by a man claiming to be a law enforcement officer.

The Kansas City Star reports the 18-year-old woman told police a man driving a white Crown Victoria with lights on the front dash pulled her over before 10 p.m. Monday on U.S. 69 in Miami County.

She says the man was in his early to mid-20s, 5-feet-9 inches tall or shorter, and wearing a Polo-type shirt with a law enforcement badge sewn onto the chest. She also described him as having a mustache and goatee, with a gun and badge on his belt.

Osawatomie police are asking for anyone who might have witnessed the alleged assault to contact them at 913-755-2101.
