WOODBRIDGE, Va. -- Police in Prince William County said they have arrested a man in a sexual assault and police impersonation investigation.

Police said that on Thursday at 3:55 p.m., a man used Craigslist.com to arrange a one-hour massage at his house in the 13100 block of Kumar Court in Woodbridge. A 19-year-old woman went to the home to perform the massage.

At one point, the man pulled out a knife, handcuffed the woman and sexually assaulted her, police said. The man told the woman he was a police officer before letting her go.

Michael Frese, 24, is charged with rape, forcible sodomy, abduction with intent to defile and impersonating a police officer. He was arrested Friday.

Frese will be held without bond until he appears in court on Nov. 21.
