A US man has claimed to have found a video tape allegedly showing R. Kelly "sexually abusing underage African-American girls."

Axar.az reports citing BBC.

Gary Dennis told reporters that he handed the tape to authorities after discovering it at his house.

R. Kelly was charged last month with 10 counts of aggravated criminal sexual abuse involving four alleged victims, three of whom were minors.

The R&B artist has denied appearing in the video, and all other charges.

If convicted, he faces three to seven years in prison on each count.

Mr Dennis, a nursing home worker, said he came across the footage whilst sorting through a box of old video tapes.

He played one tape with a recording of a football match after finding it had been labelled "R. Kelly". He expected it to have been recorded over with an old concert.

Instead it contained sexual abuse, he alleges.
