Paris Hilton's brother posted a photo of his battered and bloodied face after he told police he was attacked at a party Friday in Miami.
According to a police report obtained by ABC News, an unidentified man struck Barron Hilton, 24, in the face after the two had an argument at a party in a Miami Beach home. The report said Hilton suffered deep cuts to his forehead and nose.
Witnesses told police that the suspect wanted Hilton to "leave" the party and hit him in the face with an "unknown object," according to the police report. The suspect then reportedly fled in a dark green SUV.
Neither Hilton nor two witnesses could identify the suspect. A Miami Beach police spokeswoman told ABC News that police had not identified a suspect either.
Hilton refused treatment from fire rescue workers, the report said. A day later, he posted a photo of his injured face on Instagram.
Hilton's other sister, Nicky Hilton, later tweeted about the incident when she wrote, "Bad things happen when you hang out with bad people."
