A former Nassau County, N.Y., cop who is accused of spending more than 50 nights in his mistress's bed when he was supposed to be on patrol was arrested Friday, the New York Post reported.

According to the newspaper, the charges against Michael Tedesco, 43, include 80 counts of official misconduct, 25 counts of falsifying business records, and four counts of tampering with business records.

“Ultimately, not every lapse in judgment amounts to a crime,” Tedesco's lawyer, Aida Leisenring, told the Post.

Tedesco, who is married with two children and an 18-year police veteran, retired from the force this past spring after his trysts became public. He is collecting a full state pension, the Post reported.

According to the New York Daily News, a police internal affairs investigation found that Tedesco visited the Massapequa home of his mistress, Tara Obenauer, at least 57 times while he was supposed to be on duty.

Obenauer, a 42-year-old divorcee, told the Post earlier this year that Tedesco would park his police car outside her home and spend nights there having sex, watching TV or sleeping. His gun belt would sometimes be left within the reach of Obenauer's kids, the Post reported.

The affair, which according to the Post report began in the summer of 2011, became public when one of Obenauer's neighbors complained to police about Tedesco's frequent visits.

Obenauer has filed a legal notice saying she plans to sue Nassau County for $10 million over its failure to supervise Tedesco while on duty, the Post reported. She claimed she lives in fear of retaliation and has suffered “severe emotional and psychological damages,” according to the Daily News.
