Lindsay Lohan was arrested at 4 AM Thursday in New York City for allegedly punching a woman at a New York City nightclub.

Sources say Lohan was at Club Avenue when she got into some sort of argument with a female patron and it became physical.  Were told cops came and arrested Lindsay for allegedly assaulting her.

Law enforcement says prior to the fight words were exchanged between Lindsay and the woman as they sat in separate booths near each other.  Lindsay said something to the effect of, “Give me my space.”  Some time passed and then, for some reason, Lindsay allegedly punched the girl in the left side of her face.

By the time cops arrived Lindsay had left the club and was a passenger in a car that was leaving the area.  Cops intercepted the car and made the arrest.

And this isnt Lindsays only legal problem. She is also about to be charged with lying to cops in June after her car accident on Pacific Coast Highway.  She told them she was a passenger in the Porsche when actually she was driving.

And, if Lindsay is formally charged with the latest crime, it could trigger yet another probation violation.
