In the report, which was published on Wednesday (November 8), Haim told others, including former actor, Dominick Brascia, about the incident that occurred during the filming of the 1986 project. Sheen would have been 19 at the time.

"Haim told me he had sex with Sheen when they filmed Lucas," Brascia told the 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."

Later in the report, the National Enquirer revealed that Haim's closest friend, Corey Feldman, alluded to the alleged incident in his book, Coreyography: A 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 in the book.

The actor released a statement through his reps to The Hollywood Reporter in response to the claims, saying "Charlie Sheen categorically denies these allegations." Los Angeles police confirmed to THR on Wednesday that an investigation had been opened into Feldman's accusations.
