Charlie Sheen has been accused of raping a 13-year-old actor.

Actor Charlie Sheen has been accused of sodomising an underage boy on the set of the 1986 movie Lucas.

Speaking to The National Enquirer, former actor Dominick Brascia said his friend – late The Lost Boys star Corey Haim, who died in 2010 at age of 38 from pneumonia – confided in Brascia before his death.

Brascia said Haim told him how he was raped by Sheen while filming Lucas, when Sheen was 19 and Haim only 13. Now, Brascia has taken the allegations public.

“Haim told me he had sex with Sheen when they filmed Lucas,” Brascia told The National Enquirer. “He told me they smoked pot and had sex. He said they had anal sex. Haim said after it happened Sheen became very cold and rejected him. When Corey wanted to fool around again, Charlie was not interested.”

The publication claims it’s been conducting a “five-year long” probe into peadophelia and child abuse in Hollywood, and reports Brascia isn’t the only person to accuse Sheen.

Brascia's story also echoes that of actor and singer Corey Feldman - another of Haim's friends and former child actor - who described instances of sexual assault towards minors in his 2013 memoir.

"At some point during the filming [of Lucas] Haim explained an adult male convinced him it was perfectly normal for older men and younger boys in the business to have sexual relations, that it was 'what all guys do'," Feldman wrote, without identifying the offenders.

"So they walked off to a secluded area between two trailers during a lunch break for the cast and crew. And Haim, innocent and ambitious as he was, allowed himself to be sodomised."

The National Enquirer has also published reports from women and girls who worked on the set of Lucas and claim Sheen propositioned them with inappropriate touching and kissing.

According to the publication, Sheen denied having sex with Haim but has not responded to the most recent allegations.
