Man who exposed Jimmy Savile claims there's another 'untouchable' paedophile he's trying to bring down

The man who exposed Jimmy Savile's sickening crimes has revealed there's another 'untouchable' paedophile he's trying to bring down.

Criminologist and former police detective Mark Williams-Thomas is known for uncovering the evil sex abuser in the 2012 ITV documentary The Other Side of Jimmy Savile, which exposed Savile as a prolific child sex abuser. 

Following the documentary and subsequent coverage on the claims, police launched Operation Yewtree, a widespread investigation into the child sex abuse allegations made against the former DJ.
