Lindsay Lohan told law enforcement officials that she was attacked by a 25-year-old man she met at the Chelsea night club 1 Oak and brought back to her hotel room in Manhattan with a group of friends.
After taking his cell phone away he reportedly threw her on the bed and scratched her.
She ran out of the room and into the stairwell then back into the room where he choked her and threw her to the ground a second time.
Friends eventually pulled him off and he was arrested while still in the hotel.
The suspect has been identified as Christian LaBella, a Republican originally from California who works for Illinois Representative John Shimkus and is the nephew of Chelsea Lately writer and round-table regular Heather McDonald.
LaBella was thought to be facing counts of harassment and assault but TMZ reports that the charges were dropped.
