PORTLAND, Maine (AP) — A Massachusetts man accused of helping a disabled woman escape from a group home and then sexually assaulting her at his summer residence in Maine has been indicted.

The Portland Press Herald reports (http://bit.ly/1OTMLIS) 58-year-old William Duffy of Attleboro, Massachusetts, was indicted by a Cumberland County grand jury on 54 felony charges, including gross sexual assault and possession of sexually explicit material.

Duffy was arrested May 3. Sgt. Paul Thorpe says deputies responded after a woman called for help while being assaulted at Duffy's summer home in Sebago, Maine. Thorpe says Duffy had corresponded with her on a website for abused women before helping her escape from a group home in Carver, Massachusetts.

Police say the woman didn't have the mental capacity to consent to sex.

A phone number listed for Duffy has been disconnected.
