A former New York police officer accused of performing on tour with his heavy metal band “Cousin Sleaze” during the two years he claimed disability benefits pleaded guilty on Tuesday to mail fraud…

Christopher Inserra, 32, who served for five years with the Port Authority of New York and New Jersey, faces up to two years in prison when he is sentenced on August 5 at U.S. District Court in Brooklyn…

He claimed he was unable to perform his police duties because of a work-related injury from June 2010 until March 2012, filing for disability while continuing to collect his $90,000 annual salary…

The officer claimed he hurt his right arm in an on-the-job injury that caused excruciating pain and loss of mobility…

During the same time period, Inserra was the lead singer with the Brooklyn band “Cousin Sleaze,” whose “Sick Maniacs” album features such songs as “Infection” and “Walk of Shame,” according to court documents.

Video footage of his band performing in Northeast bars and on an East Coast “Miles of Mayhem” show the muscular lead singer in a tank top slashing the air with his well-toned right arm while gripping a microphone…

The court says he’s started paying back some of the disability checks he received. The record says nothing about the salary he received at the same time. Cousin Sleaze, eh?
