Star Trek icon George Takei has been accused of sexually assaulting a former male model while the young man was passed out in his Los Angeles condo in 1981.

Scott Brunton came forward to say he was groped by the actor when he was just 24, claiming Takei - then aged 43 or 44-years-old - took advantage of him just after a breakup.

'This happened a long time ago, but I have never forgotten it,' Brunton told the The Hollywood Reporter.

'It is one of those stories you tell with a group of people when people are recounting bizarre instances in their lives, this always comes up. I have been telling it for years, but I am suddenly very nervous telling it.'

Scott Brunton said he met Takei in 1981 when he was living in Hollywood and had just broken up with his boyfriend. Takei is pictured (above) as his character Hikaru Sulu on the hit television show Star Trek in 1969

The former model said he encountered Takei when he was living in Hollywood and working as a waiter at the beginning of his career at Greg's Blue Dot Bar.

He said he exchanged numbers with the actor, and on occasion the pair called each other or ran into each other at different clubs.

When Brunton broke up with the man he was dating at the time, he told Takei, who took the opportunity to invite the model to dinner and the theater.

'He was very good at consoling me and understanding that I was upset and still in love with my boyfriend,' Brunton told THR.

After dinner that night the two men went back to Takei's home for a drink.

Just a few sips into his second drink, which Takei made for him, he said he started feeling unwell.

'I have the second one, and then all of a sudden I begin feeling very disoriented and dizzy, and I thought I was going to pass out,' he explained.

'I said I need to sit down and he said sit over here and he had the giant yellow beanbag chair. So I sat down in that and leaned my head back and I must have passed out.'

He said that after a while he woke up with his pants around his ankles and Takei groping his crotch and trying to get his underwear off.

'I came to and said, "What are you doing?" I said, "I don't want to do this," Brunton told THR.

'He goes, "You need to relax. I am just trying to make you comfortable. Get comfortable."'

Brunton said he he managed to gather enough strength to push Takei off of him and then went to his car and waited until he felt well enough to drive himself home.

'That was that,' he said of the encounter.

Four of Brunton's close friends told THR that he had confided in them about the alleged assault years ago.

Now, years after the incident, he said he is coming out with his story after seeing Takei's statement about Kevin Spacey to THR on October 30.

After Anthony Rapp alleged that Spacey took advantage of him, the actor used the opportunity to come out as gay.

Takei apparently took offense to that, and aid: 'Men who improperly harass or assault do not do so because they are gay or straight - that is a deflection,' in a statement to THR.

'They do so because they have the power, and they chose to abuse it.'

Brunton said the response infuriated him.

Takei's representative, Julia Buchwald, didn't outright deny the allegations to THR, but said they cannot give his comment at the present time.

'George is traveling in Japan and Australia and not reachable for comment,' she said in a statement.

The 80-year-old rose to fame in his role as Hikaru Sulu in the original Star Trek television series. Since then he has become an outspoken activist advocate for LGBTQ rights.
