Ross Kemp left in disgust after interviewing a paedophile in prison who claimed children enjoy the sexual encounters.
The former EastEnders star went into prison for an ITV documentary titled Ross Kemp Behind Bars: Inside Barlinnie.
There, he sat down to talk to a paedophile who has been caught with child pornography three times.
The man told Kemp that he should be out of prison since he is "no harm to anyone".
"Do you not think these children in the pictures are forced to be photographed?" Kemp asks him.
