NEW YORK (AP) — A law enforcement official says a 25-year-old man got into an argument with Lindsay Lohan in her New York City hotel room over photos on a cellphone and she was physically grabbed or thrown.

The official was not authorized to speak publicly about the encounter Sunday morning and spoke to The Associated Press on condition of anonymity.

Authorities confirm that Christian LaBella of Valley Village, Calif., was taken into custody around 6 a.m. He faces a misdemeanor assault charge.

Lohan's publicist says she not hospitalized 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.
