After being sentenced Wednesday to 18 months probation for assaulting his wife last year, Thomas LaCroix resigned as police chief of Waltham.
Waltham Mayor Jeannette McCarthy said she was notified of LaCroix’s resignation from the police department Wednesday afternoon.
LaCroix had been on unpaid leave since he was convicted by a Concord District Court jury last month of assaulting his wife twice in their Maynard home on June 12 last year.
Judge J. Elizabeth Cremens sentenced LaCroix earlier in the day Wednesday. The judge ordered LaCroix to undergo an evaluation to determine if he needs to take a course designed to rehabilitate batterers. He will face another evaluation on whether he will be allowed to drink alcohol during the probation period.
