A second former Charles In Charge actor on Wednesday accused the show’s star, Scott Baio, of misconduct on the set of the 80s sitcom when they were underage. Baio has vehemently denied all the claims against him.

Alexander Polinsky, who played Adam Powell, said he was harassed by Baio, who was then in his 20s, and “ultimately assaulted by him, between the ages of 12 and 15 years old.”

Flanked by attorney Lisa Bloom at a Los Angeles press conference, Polinsky, now 43, said he was called a “faggot” by Baio and told about “gay sex acts” that that he would “grow up to perform.”

“Scott pulled down my pants in front of over 100 people,” Polinsky said. “Another time, he laughed as he cut a hole in the canvas wall of my private dressing room on set and exposed his genitals to me.”

Describing Baio’s behavior as “unrelenting” and “sexual-themed hazing,” Polinsky also Baio threw hot water in his face at one point.

He said the abuse began when he was 11 after he stumbled upon Baio acting inappropriately with costar Nicole Eggert, then 14.

“I want a public apology,” Polinsky said. “If children are going to continue working in entertainment, they must be protected.”

Also at Wednesday’s press conference was Eggert, the first Charles In Charge actor to accuse Baio of misconduct.

Eggert told NBC last month that Baio manipulated her into intercourse when she was 17. She also said he penetrated her with his finger when she was 14.

Polinsky also told NBC in January that Eggert had previously told him of the abuse.

Baio, who has been most prominent in recent years for his vocal support of conservative politics, has denied all the allegations against him.

He has admitted to having sex with Eggert, but said this happened after she turned 18 and that she seduced him.

On Twitter on Wednesday, Baio wrote, “I’ve tried my best to let the proper authorities handle this matter. It now seems they want a ‘horse & pony’ show.”

The actor said he would hold his own press conference later on Wednesday afternoon.

Eggert, 46, expressed remorse at Wednesday’s press conference for not standing up for Polinksy.

“As an adult I carry huge guilt that I was apart of this in any way,” Eggert said. “I feel horrible and guilty that I didn’t stand up for him at the time, but I myself was a child. We were children.”

“It was hard for me to stand up for anyone else when I was trying to find my own truth,” Eggert said.

She said Polinsky was “consistently picked on” by Baio. “[He was] tripped, pushed around, berated with horrendous, horrendous homosexual slurs — all because he was in the wrong place at the wrong time and witnessed something he wasn’t supposed to see.”

“Our innocence was robbed of us,” Eggert said. “What was supposed to be the best time of our life was a living nightmare.”
