Not a day passes without fresh allegations of sexual assault and impropriety by beloved comedian Bill Cosby. And in an exclusive interview with the New York Daily News, veteran NBC employee Frank Scotti, 90, has come forth with details of how the misconduct was kept under wraps.

Cosby had Scotti delivering monthly payouts to eight different women in 1989-90 - including Shawn Thompson, whose daughter Autumn Jackson claimed the actor was her father.

Scotti told the Daily News: "I suspected that he was having sex with them because the other person he was sending money to (Thompson) he was definitely having sex with. Why else would he be sending money? He was sending these women US$2,000 (S$2,500) a month. What else could I think?"

He claimed the comedian would give him a bag of US$100 bills to be disbursed as money orders of varying amounts in Scotti's name. Scotti said he kept receipts from the money orders he allegedly sent.

"I did a lot of crazy things for him," he added. "He was covering himself by having my name on it. It was a coverup. I realized it later."

He said he decided to speak up as the chorus of sexual abuse allegations against Cosby, 77, grew steadily louder. "I felt sorry for the women," he told the Daily News.

Scotti worked as facilities manager at the Brooklyn studio where The Cosby Show (1984-1992) was originally taped before a live audience.

Although Cosby has not been charged with a crime, according to AFP, some 20 women have now made on-the-record claims of sexual assault dating back to the 1960s.

Actress Michelle Hurd, 47, posted on her Facebook page that Cosby was "VERY inappropriate" with her when she did stand-in work on The Cosby Show. She said that she was subjected to "weird acting exercises where he would move his hands up and down my body, (can't believe I fell for that)".

She is best known for the crime drama Law & Order: Special Victims Unit and the post has since been taken down.
