BOSTON (AP) – A 35-year-old Maine man was arrested Wednesday in connection with a string of assaults and robberies of women employed by escort services in Boston.

Acting on a tip they received after publicly releasing a photo of the suspect, Boston police traveled to Kittery, Maine, where they assisted local police in the arrest of Robert Davis at his home. Police said Davis closely resembled the man in the photo, which was taken from a surveillance video.

A search of the house yielded a stun gun believed to have been used to temporarily disable two of the victims. Investigators also found mace, plastic ties allegedly used to restrain the victims, cash, a woman’s Rolex watch and other jewelry, and clothes matching the description of those worn by the attacker in at least three of the attacks, police said.

Police believe Davis is responsible for at least four attacks on escorts in various Boston hotels.

“We’re hoping more people will come forward if in fact they were victims,” Boston police spokesman Cliff Connolly said.

Davis had inside knowledge of the workings of the escort service industry due to prior employment with a Web site, police said.

Kittery Police Sgt. Ron Avery said Davis, who is apparently unemployed, has lived in the town for about three years and had no criminal record in Maine.

Davis was being held in the York County Jail in Alfred, Maine, and was scheduled to appear Friday morning in Biddeford District Court on a fugitive from justice charge.

He will likely be returned to Boston to face criminal charges, including kidnapping, armed robbery and armed assault in a dwelling, Connolly said.
