SYRACUSE, N.Y. -- An Oswego County man is behind bars in Syracuse, accused of raping a woman and impersonating a detective.

Arthur Groff, 37, of Hastings, faces a number of charges, including rape, sexual abuse and unlawful imprisonment.

Authorities say on Thursday, Groff responded to an ad in a Syracuse paper. The woman who placed the ad says Groff made her take her clothes off, then accused her of exposing herself to an undercover officer, even displaying a badge.

The woman says Groff handcuffed her and then raped her.

Groff is being held at the Onondaga County Justice Center and will be arraigned Saturday.
