A man has been arrested in New York City after allegedly assaulting actress Lindsay Lohan in her hotel room.

The Mean Girls star was partying at nightclub 1 Oak on Saturday night (29Sep12) when she invited a guy she had just met back to her suite at the W Hotel in Manhattan's Union Square to continue hanging out with her friends.

However, the late night gathering ended abruptly when Lohan pulled the fire alarm and called the police to her suite after getting into an altercation with the man, who has since been identified as Christian LaBella.

The argument was reportedly started after she spotted several photos of herself on his cell phone.

According to local news station NBC New York, the 26 year old claims LaBella grew angry after she confronted him about the snaps, allegedly prompting him to attack Lohan, choking her and throwing her to the ground before the actress' pal was able to restrain him.

The star only sustained minor scratches to her hands and refused medical help.

A rep for the star tells Wenn, "Lindsay was assaulted early this morning in a New York hotel. While she did sustain some injuries, she was not hospitalized. The assailant was arrested and is currently in police custody. Lindsay has spoken with police and is fully cooperating with the investigation."

LaBella, 25, has since been charged with two counts of assault and two counts of harassment.
