A former "Charles in Charge" actor says Scott Baio assaulted and "mentally tortured" him during their time together on the show in the 1980s. "Scott pulled down my trousers in front of 100 people at the same time he laughed as he cut a hole in the canvas wall of my private dressing room and exposed his genitals to me".
Baio responded to Polinsky's allegations in a statement through his represenatives.
He said the abuse began when he was 11 after he stumbled upon Baio acting inappropriately with costar Nicole Eggert, then 14.
He has admitted to having sex with Eggert, but said this happened after she turned 18 and that she seduced him.
"I was sexually harassed by Scott Baio and ultimately assaulted by him between the ages of 12 and 15 years old", Polinsky told a gathering of reporters.
Baio had no immediate comment about Polinsky's latest accusations on Wednesday.
He also detailed an incident in which Baio called him a "f.t".
Polinsky, 43, claimed that Baio, 57, bullied him for years with homophobic remarks, in addition to pulling down Polinsky's trousers in front of the crew of the '80s sitcom and throwing a cup of hot tea in his face.
UPDATED Feb. 14, 2018, 5:46 p.m. ET with comment from Scott Baio's attorney. Nicole Eggert was the first.
The series Charles in Charge aired between 1984 and 1990; in the wake of his fame from the iconic comedy Happy Days, at the time Baio was arguably at the height of his celebrity power. Both the actors claim that the abuse continued throughout the run of the show. I wish to be a small part of the change in the world.
"I want a public apology", Polinsky said.
McGrath showed a photo of a smiling Polinsky and Baio that she said was taken at Baio's birthday party seven years ago.
A third actor who worked briefly on the show, Adam Carl, earlier posted on social media he was aware of the alleged abuse of Eggert. It is abhorrent. Both Nicole and I were minors. The LAPD has confirmed to USA TODAY that they are looking into the allegations.
"Our innocence was robbed of us", Eggert said. After Polinsky's press conference, Baio spoke with TMZ and made his plans to sue his former co-stars and their lawyer known. Baio did not attend the news conference in person.
According to Polinsky, during the first season of the show, he walked in on Eggert sitting on Baio's lap.
They said Baio would cooperate with any Los Angeles Police Department investigation.
Spokesman Brian Glicklich read a statement from the actor at a news conference held Wednesday.
The allegations "threaten everything that's important in my life", the statement said. In addition to denying all of the allegations, the reps went on to attack Nicole Eggert and Alex Polinsky's attorney, Lisa Bloom, for representing Harvey Weinstein.
In Polinsky's telling, this was only one example of what he described as "a pattern of abuse that was unrelenting".
