A 54-year-old Tuckahoe man who worked as a driver and counselor at a group home for disabled adults in Ossining has been charged with repeatedly raping one of the female residents.

Anthony Fontaine was taken into custody by Westchester County police Wednesday. His indictment was sealed Wednesday.

The Westchester County district attorney's office said that from Oct. 22 to Dec. 24, 2011, he committed numerous sexual attacks on the victim, who lived at the Ossining House. Her complaints to an attendant triggered an investigation by the Westchester County police and the Sex Crimes Bureau of the district attorney's office.

Fontaine is charged with 14 felony counts: three counts of first-degree criminal sexual act, two counts of first-degree rape, four counts of first-degree sexual abuse, two counts of third-degree rape and three counts of third-degree criminal sexual act.

Fontaine was being held in the Westchester County Jail in lieu of $75,000 bail. His next court appearance is scheduled for July 3. If convicted, he faces up to 25 years in state prison on each count of first-degree criminal sexual act and first-degree rape.

Fontaine's attorney, Christina T. Hall, said her client had cooperated with investigators and voluntarily surrendered Wednesday.

"Mr. Fontaine has maintained his innocence," she said, and suggested that the six-month gap between the beginning of the investigation in December and the arrest in June pointed to a weak prosecution case.
