Oscar-nominated actor Leonardo DiCaprio was assaulted early Friday morning at a party at the Hollywood Hills home of Rick Salomon, PEOPLE reports exclusively.
In a statement released to PEOPLE, the actor's publicist, Ken Sunshine, says: "While leaving a small private gathering, Leo was attacked by a woman who was trespassing and had been repeatedly asked to leave the property. The attacker struck him with a glass object before being restrained by witnesses. The woman was reportedly looking for an ex-boyfriend, who she had apparently physically assaulted on prior occasions."
DiCaprio was at a small party hosted by Salomon (Paris Hilton's ex, who starred with the hotel heiress in their notorious sex video), when at around 4 a.m., the woman hit him in the face with what appeared to be a beer bottle, a source reports. After the incident, an ambulance wasn't called but friends took him to a hospital for medical attention, where he received about a dozen stitches near his ear, says the source.
The actor, who is in Los Angeles on a break from shooting the Martin Scorsese-directed movie The Departed in Boston and New York, is not expected to have the incident affect his return to the set.
Law enforcement authorities have begun a criminal investigation into the matter, according to DiCaprio's publicist.
