Child star Corey Feldman says that actor John Grissom, an adult co-star on several films Feldman worked on in the 1980s, was one of the men who molested him as part of a Hollywood "child sex ring."

Feldman revealed Grissom's identity on an episode of The Dr. Oz Show, which aired Thursday.

In the clip seen here, Feldman names his alleged attacker, as Dr. Mehmet Oz, the show's host, shows the audience a picture of Grissom on his cell phone. Moments after Feldman confirms the photo is of his abuser, the pair make a phone call to Los Angeles authorities.

“That is him,” Feldman says of Grissom's photo in the clip. “That is the guy.”

This is the first time Feldman has actually named Grissom as a member of what he claims is a "Hollywood child sex ring" that has preyed on young male actors since the 1980s. Grissom co-starred with Feldman in the early 80s movies, License to Drive and Dream a Little Dream.

Feldman told Oz that he wanted to name Grissom in his 2013 memoir, but that his legal representation at the time forced him to use a pseudonym, "Ron Crimson."

“We had to change the names legally,” Feldman said. “The lawyers made me change the names. ... They gave me a list of three or four, you know, names. I picked the one that sounded closest to his name.”

Feldman has been making claims about Hollywood abuse for years, but was largely ignored until just this month, when stories began to emerge that mega-producer Harvey Weinstein, Oscar-winner Kevin Spacey, and director James Toback, among others, had allegedly harassed, abused, and even attacked young actors and actresses in Hollywood.

Suddenly, Feldman's claims didn't seem so out of place. Urged to name his abusers, earlier this week Feldman said he was consulting with lawyers and wanted to make sure he was fully protected before going completely public. On Monday, on the Today Show, Feldman said child talent manager and convicted sex offender Marty Weiss was among his abusers.

Feldman urged Grissom to turn himself into authorities. “Now is your time,” Feldman said on Oz's show. “Be a man for the first time and come forward yourself. Let it be known and you will be dealt with in a much more tolerant way, I’m sure. However, if you do not, we are coming for you.”

Grissom has not commented on the allegations.
