He spoke out in Midtown, Manhattan on Sunday with attorney Gloria Allred, CBS2’s Lisa Rozner reported.

The man said he does not know R. Kelly, but claims he found an old VHS tape from the 1990s that is evidence Kelly abused girls. He said he had a “moral duty” to give the tape to law enforcement and contacted Allred.

Gary Dennis and his wife, Sally, spoke out over a tape that Gary said he discovered while cleaning out a box of sports games. One tape also had R. Kelly’s name on it.

“I watched the sports on the tape and then continued to watch what I thought would be an R. Kelly concert. To my shock and surprise, R. Kelly appeared to be on the tape, but not in concert. Instead, he was sexually abusing underage African-American girls,” Dennis said.

That’s when Dennis said he contacted attorney Allred, who represents women who say they were abused by Kelly.

“This is not just child sexual abuse, which is bad enough, but it is also child pornography,” Allred said.

Allred wouldn’t discuss specifics on the tape, but said it appears to show a separate incident from the 10 counts of aggravated sexual abuse in Chicago, involving four women. Prosecutors said three of them were underage at the time of the alleged abuse. Last month, Kelly, a three-time Grammy-winning artist, pleaded not guilty.

And he recently sat down for a wide-ranging interview with CBS This Morning anchor Gayle King.

“I didn’t do this stuff. This is not me. I’m fighting for my (expletive) life. Ya’ll killing me with this (expletive),” Kelly said.

On Saturday, Kelly was released from a Chicago jail after failing to pay child support. As for Sunday’s allegations, his attorney told the Associated Press Kelly denies that he is on tape with any underage girls.

“I believe that there are other tapes in circulation and that individuals who possess them may be reluctant to admit they have possession of them,” Allred said.

Allred said the tape from Dennis was turned over to the U.S. Attorney for the Eastern District of New York. She didn’t say why it went there. A spokesperson for that office told CBS2 it cannot comment on whether it is investigating or if it even has the tape.
