Actress Lindsay Lohan got into an argument with a man in her New York City hotel room over photos on a mobile phone and she was physically grabbed or thrown, police said .
Authorities confirmed that Christian LaBella, 25, of Valley Village, California, was taken into custody early today. He faces a misdemeanour assault charge.
Lohan's publicist says she was not taken to hospital and is cooperating with the investigation.
Police acknowledge that LaBella was arrested but declined to identify the other party because that person is the alleged victim of assault.
Lohan was accused last week of clipping a pedestrian with her car. Her publicist said he expects those allegations to be proven false.
