NEW YORK (AP) -- Lindsay Lohan got into an argument early Sunday with a 25-year-old man in her New York City hotel room over photos on a cellphone and she was physically grabbed or thrown, a law enforcement official said.
The official was not authorized to speak publicly about the encounter Sunday morning and spoke to The Associated Press on condition of anonymity.
Christian LaBella of Valley Village, Calif., was taken into custody around 6 a.m., authorities confirmed. He faces a misdemeanor assault charge and a harassment charge. He was still in custody Sunday afternoon and could not be reached for comment.
Police acknowledged that LaBella was arrested but did not identify the other party because that person is the alleged victim of assault.
The official said Lohan and LaBella had encountered each other earlier in the night at a club. It was unclear whether they had met before.
Lohan was injured but not hospitalized, her publicist, Steve Honig, said in a statement.
"Lindsay has spoken with police and is fully cooperating with the investigation," he said. He declined to comment further.
Lohan herself has had several run-ins with law enforcement.
Last week, Lohan, 26, was accused clipping a pedestrian with her car outside a nightclub and driving away. She was given a ticket and was scheduled to appear in court Oct. 23. Honig has said he expects those allegations to be proven false.
The actress was also involved in a car accident in California this summer that sent her and an assistant to a hospital, but didn't result in serious injuries for anyone. The accident remains under investigation.
In May, she was cleared of allegations that she struck a Hollywood nightclub manager with her car.
Lohan remains on informal probation for taking a necklace from a jewelry store without permission last year. That means she doesn't have to check in with a judge or probation officer but could face a jail term if arrested again.
Lohan recently filmed "The Canyons," a movie by "Less Than Zero" author Bret Easton Ellis.
