Police are investigating an incident involving actor Corey Feldman who claims he was attacked while sitting in his car at a red light in Los Angeles.

Feldman’s car was stopped at 10:45 PM Tuesday, a police spokesman says, when someone opened the door and made “a stabbing motion with an unknown object.” LAPD Sgt. Barry Montgomery tells Deadline Feldman was not stabbed, had no lacerations and no additional injuries and drove himself to the hospital. He is said to be in good condition. The LAPD does not have a suspect description, nor has it determined what weapon was used in the alleged attack.

Feldman later tweeted from his hospital bed that he was in the car with his security when he was targeted by a “wolfpack.”

Montgomery confirmed LAPD have taken a report on the incident and are investigating.

Los Angeles police had previously investigated Feldman’s claims about a long-running Hollywood pedophilia ring. Feldman says he and his friend Corey Haim were both molested by industry figures when they were young actors. Haim died in 2010 at age 38. Last November, the LAPD ended an investigation into the allegations, saying the incident was outside the statute of limitations.
