LOCKPORT — Michael Collette, the city firefighter suspected of playing an extra in a movie being filmed in Buffalo while off the job on disability, resigned Tuesday, the day before a scheduled disciplinary hearing aimed at firing him. But the city isn’t done with him yet.

Mayor Michael W. Tucker said Wednesday that the city wants Collette to pay back the money he received in workers’ compensation benefits while off duty since March 2009.

“We’re certainly interested in getting our money back. We’re going to do what we have to do to get it,” Tucker said.

City officials told The Buffalo News three weeks ago that the state Workers’ Compensation Board was preparing to charge Collette with a felony for allegedly defrauding the compensation system by working while on disability.

The News published photos on its Web site in December showing someone who strongly resembled Collette playing the role of a security guard in the Keanu Reeves movie “Henry’s Crime” as a bank robbery scene was being shot in Buffalo.

Collette never confirmed he was the actor, but in December he did say that his side business, Mac Limousine, was providing transportation services to the filmmakers.

Collette, 45, has been paid $516.50 a week from the city’s self-insurance fund since he went off active duty.
