New York- Teen starlet Lindsay Lohan’s boozing, bruising father will stay out of jail by checking into rehab, Long Island prosecutors said yesterday.

Michael Lohan, 44, who was charged with assaulting one brother-in-law and threatening another, struck a plea deal that includes in-patient treatment followed by probation. Lohan was accused of using the heel of his shoe to bludgeon Michael Sullivan, the brother of his estranged wife, on May 23.

Two days later, he allegedly made threatening phone calls to another brother-in-law, Paul Sullivan, and to his wife, Rose.

From the NY Post: MICHAEL Lohan – the disputatious dad of Lindsay Lohan – says his reputation is being unfairly destroyed by the “lowlifes” living off his daughter.

“Her friends are parasites and I said so, so they scorn me,” Lohan told PAGE SIX yesterday after appearing in Nassau County Supreme Court on charges he assaulted his brother-in-law last May. “They’re trying to put a wedge between me and my daughter.”

Lohan – who agreed to enter drug and alcohol rehab within the next three weeks to avoid jail time – said, “I don’t have a drinking problem.”

He said his relationship with Lindsay is fine: “We love each other. But the people around her are lowlifes. It’s all dese, dem or dose. I have tapes you won’t believe, and I’ll release them at the proper time.”

Lohan blames Lindsay’s publicist, Leslie Sloane Zelnick, for spreading rumors that he’s an out-of-control alcoholic with anger-management issues. “Leslie Sloane is a phony,” Lohan said. “We don’t like each other one bit.” Zelnick declined to comment.

He gave a detailed account of the night two weeks ago when he “happened to be passing by” and saw his wife, Dina, the mother of his four children and manager of Lindsay’s career, coming out of her Midtown office at 2 p.m. He followed her to Cipriani.

“I wanted to talk to her about the kids, but she wouldn’t stop,” Lohan recalled. “I talked to the maitre d’ and told him, ‘Don’t let her drink. She drove here.’ ”

When she wasn’t at the family home in Baldwin, L.I., by 9 p.m., Lohan said, “I called her on the cellphone and she was sloshed. I thought the kids were with her, so I called the cops.”

Dina arrived home an hour later and Michael pulled into the driveway behind her. “She tried to jump the curb and nearly ran me over,” Lohan said. “Dina’s assistant, Ann Occhupinti, got out of the car and said, ‘You want a piece of me?’ She’s 200-plus pounds. She’s bigger than me. I backed away.”

Lohan, who filed a complaint of reckless endangerment with Nassau County cops, said by the time the police came to give Dina a Breathalyzer, “she was already at her mother’s place. She was hiding from the police.

“My lawyer, Dominic Barbara, and Nassau Asst. DA Barbara Kornblau have been fantastic in getting to the bottom of this.”

Det. Robert Pescitelli confirmed, “It’s an open case that’s being investigated.”
