The married Long Island cop who allegedly spent nights in his girlfriend’s bed with his marked cop car in her driveway – while he was supposed to be on patrol — pleaded not guilty today to nearly 100 counts of misconduct.

Former Nassau Officer Mike Tedesco has been arraigned on a 109-count indictment that cites GPS tracking to show he was actually dating two different women.

State Supreme Court Justice Anthony Marano set bail at $10,000 bond or $5,000 cash. Tedesco is due back in court on Jan. 9

Tedesco, 43, did not comment as he was led in to the DA’s office early this morning following his arrest.

“Ultimately, not every lapse in judgement amounts to a crime,” said his lawyer, Aida Leisenring.

The charges include 80 counts of official misconduct, 25 counts of falsifying business records, and four counts of tampering business records. He faces up to 7 years in prison if convicted.

Tedesco’s wife, Sharon, was in court today supporting her husband.

The Post broke the story in April. Tedesco, 43, spent more than 100 nights while on duty at the home of Massapequa divorcee Tara Obenauer — having sex, watching TV, and napping, she told The Post at the time. He would lay his gun belt at the foot of bed.

Tedesco told Obenauer he let other, younger officers answer police calls, so he could goof off on the public payroll while collecting his $175,000 salary. She said he called the other cops “my assist bitches.’’

Obenauer believed Tedesco, 43, was divorcing his wife, but, when Internal Affairs cops came to her door in February, she found out he was still married and he was also cheating on her, she said.

Tedesco was caught after one of Obenauer’s neighbors became angry at the sex-break cop’s brazen dereliction of duty and called Police Headquarters, source said.

After the scam appeared in The Post, Tedesco quickly put in for retirement and is currently collecting a state pension. Nassau has refused to grant him additional accrued pay — but he is disputing that.

Obenauer later filed an unusual notice of claim against the county – claiming they owed her $10 million for allowing Tedseco to seduce her under false pretenses.

She said their relationship began in July, 2011, while she was struggling with breast cancer chemotherapy. Another cop came to her home on a routine call and told the prowling Tedesco that she was pretty, she said.

About a month later, she and Tedesco began a romantic relationship. Tedesco lounged at Obenauer’s lavish waterfront home while on duty, she said. He sometimes used his cop car to chauffeur her daughter and deliver ice cream for her kids, Obenauer said.

When he was caught by Internal Affairs cops, Tedesco called Obenauer and threatened her, she said.

“He screamed at me, ‘you f—king tell them that I’m just a friend who stops by once in a while,’ Obenauer said. “I told him, `They have your GPS records, you moron. I’m not perjuring myself for you. We’re over and I want my key,’ ‘’

Nassau Police cars are equipped with GPS recorders but the department is not allowed to track cops unless an investigation is started for another reason.

Tedesco was on the force for 17 years. Before that, Tedesco was a New York Housing cop for about four years.
