Charlie Sheen is being accused of sodomizing a then 13-year-old Corey Haim on the set of the movie 'Lucas.'

According to the National Enquirer, a now deceased Haim had told others about how he was allegedly raped as a minor by Sheen, who was 19 at the time, while filming the 1986 movie.

Former actor Dominick Brascia claims Haim disclosed to him what happened between him and Sheen. Brascia went on the record about what he says Haim told him before he died in 2010 at 38-years-old.

'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.'

Meanwhile on Wednesday, Sheen emerged from his parents Martin and Janet Sheen's home looking defiant while smoking a cigarette in the face of the bombshell allegations against him.

By the afternoon Sheen released statement through his representatives to the Hollywood Reporter saying 'Charlie Sheen categorically denies these allegations'

The magazine also says that Lost Boys actor'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.

'So they walked off to a secluded area between two trailers during a lunch break for the cast and crew,' continued Feldman,' and Haim, innocent and ambitious as he was, allowed himself to be sodomized.' Feldman never named Sheen as the man in the incident.

In 2011, according to the Enquirer, when Feldman was asked about Sheen he said: 'I'm not a huge fan of Charlie Sheen…especially the way he's affected other people that I know.'

Tellingly, Feldman also said Haim 'fought for his entire life to recover from those early experiences and to get his life together.'

And, just last week, on the Today Show, Feldman said a report coming from the National Enquirer was to be expected.

'They cover it up. They protect it. I know of a friend of mine that actually went and spoke to a reporter and gave all the information and they were -- the day before I launched my campaign, they were supposed to put out a story in the [National] Enquirer.'

Haim allegedly told several people close to him about Sheen's abuse during the filming of 'Lucas'

'I believe there's a lot of darkness in Hollywood right now, and I believe it's been there for quite some time,' said Feldman. 'It's going to continue unraveling. This is just the beginning, it's just the tip of the iceberg.'

Other sources came forward to support the claims made by Brascia about Haim's interaction on set with Sheen- who is now living with HIV.

Another insider alleges that 'Corey was so confused by the sexual encounter he believed, like so many victims, he was 'in love' with his abuser,' adding that the actor bullied the young teen actor into a vulnerable position for sex.

Brascia added that Haim told him he later had consensual sex with the 'Wall Street' star while in his mid-to-late 20s. 'Haim told me he had sex with Sheen again,' Brascia said, adding 'He claimed he didn't like it and was finally over Sheen. He said Charlie was a loser.'

According to the report, the Enquirer says they spoke with dozens of sources who say Haim told them about his alleged abuse at Sheen's hands before he died of pneumonia in 2010.

Additionally, a confidant close to Sheen claims that the 'Platoon' actor had said he had a liaison with Haim, but said it was consensual.

Other allegations in the report emerged about Sheen's behavior with at least one other minor on the set of 'Lucas,' in which the report says a total of eight set witnesses spoke out as part of the investigation.

Last year, Rossie was granted a temporary restraining order against Sheen. A judge in Los Angeles approved the order based on Rossi's claims that she's afraid of her ex due to threats he's made toward her and two 2014 incidents of alleged domestic violence

One of the women on the set claims she was just 17 when Sheen inappropriately kissed her and solicited sex from her in a bathroom: 'I [admit], I did have a thing for Sheen,' said the now 49-year-old woman, who revealed the incident happened at Chicago's Navy Pier.

'I talked with him for a long time,' she said, 'and kissed him.' However, the woman alleges, Sheen pressed for more than a kiss.

'I was in a bathroom with him at one point. He tried to get me to have sex.' She also claimed that Sheen had become increasingly 'sloppy and wasted' as the evening progressed.

Another woman who was on set claimed that she had just turned 18-years-old in time for the cast wrap party.

'He found out about [my birthday] and he grabbed me and gave me this elaborate kiss,' she said, adding Sheen had a mouthful of steak at the moment he landed a 'disgusting,' slimy, saliva-smooch on her lips: 'To this day I can remember that. Is that sad?'

The just barely 18-year-old says she shut down Sheen after the kiss.

'I had no interest in doing anything with him, so I let him know that,' she told the Enquirer. 'I didn't think he was all that special actually, like some of the girls in my class did. I actually thought he was a conceited a–hole. He was really obnoxious on the set.'

Bolstering the report, the Enquirer says in a 2006 court filing about Sheen, ex-wife Denise Richards allegedly claimed he visited websites featuring young men and girls who appeared underage.

Richards' hand signed declaration was filed to stop Sheen from getting overnight visits with their daughters.

The actress alleged he 'belonged' to 'disturbing' sites 'which promoted very young girls, who looked underage to me with pigtails, braces and no pubic hair performing oral sex with each other.'

Other sites visited by Sheen, Richards alleged, involved 'gay pornography also involving very young men who also did not look like adults.'

Brascia also claims in the report that he had witnessed Haim approach Sheen one night, while the actor was sitting at a table with two A-list stars.

He said Sheen was drunk when Haim walked over and asked, 'Hey Charlie, remember me? How you doing, Charlie?' In reply, Sheen coldly claimed he didn't know Haim, and that Sheen said: 'Who are you? I don't know who you are.'

Feldman went on the Today Show and said he knew of a report coming out in the National Enquirer about a story related to a Hollywood sex predator

His best friend couldn't save him. Feldman wrote in his memoir about alleged abuse Haim suffered during the filming of 'Lucas,' saying he explained to Haim that the behavior he experienced was not appropriate

He also says later in the evening, Brascia found himself face-to-face with Sheen who told him: 'I'm really not that drunk. I just don't like that little a–hole. I hate that a–hole. Get him out of here. He's a freaking jerk.'

Sheen also allegedly shoved Haim's mother Judy, after interacting with her in a favored Los Angeles spot saying: 'I hate your f—–g son. If I ever see him, I'm going to flush his head down the f—–g toilet. Get the f–k away from me,' before pushing her away and into a wall.

An insider said the mere mention of Haim's name to Sheen and the actor would 'shut down on me completely. There's no doubt in my mind that something went down…enough that he had a grudge against Haim forever.'

DailyMail.com reached out to Sheen's team and have not heard back.

The statute of limitations for the alleged incidents on the set of 'Lucas' which was filmed in Chicago, have long expired.

Sheen's lawyers told the Enquirer he never had sex with Haim, and they did not respond in time about other allegations from the set of 'Lucas.'
