SALEM, Mass. (AP) — A man who has been convicted eight times for groping women on Massachusetts public transportation has been sentenced to more than four years in prison for doing it again.

Dane Mullin, a former Salem resident who is now homeless, was arrested last September after authorities say he groped a female passenger on the MBTA Red Line.

The Salem News ( ) reports that the 31-year-old Mullin admitted Wednesday he violated his probation ordered after a similar crime in 2013.

He and his attorney, Meredith Reeves, have agreed to a deal under which he would serve four to five years in prison for violating his probation.

Mullin is a sex offender who has been repeatedly arrested for indecent assault and battery since he was 17.
