Ross Kemp went into a prison and met with paedophiles as part of ITV documentary Ross Kemp Behind Bars: Inside Barlinnie.
One of the men he met had been caught with inappropriate images of minors on his computer three times, leaving the former Eastenders actor disgusted. Watch how it unfolded here:

On the show, which was aired last night, the man insisted he should be allowed out as he's 'no harm to anyone'.
However, Ross asked him: "Do you not think these children in the pictures are forced to be photographed?"
And he replied: "They seem to enjoy it."
Ross then responded: "You think you should be allowed out?"
To which he received the reply: "I'm no harm to them."
Ross couldn't carry on with the interview after hearing the news and finished: "I think that's it, thank you very much for talking to me."
He then stormed off and ordered the guards: "Release me, please."
Speaking to camera, Ross then explained how 'disturbed' he was feeling.
He added: "These people will be out of prison very soon, and it's not right."
Kemp also spoke with a bunch of criminals to see what life is really like inside a prison and whether it matches up to people's expectations.
When we talked to him ahead of the programme, Ross told LADbible that drugs are a serious problem within the prison system: "Barlinnie prescribes more methadone than any other place in western Europe. What some of the prisoners do is take their methadone, regurgitate it later and then sell it for harder drugs."
He adds that some prisoners are sent socks or underwear soaked in Valium, where they just add boiling hot water and drink the solution to get high. Others get paper sent to them from the outside, which is sprayed with synthetic substances like Spice or Black Mamba.
Across the UK, the number of assaults has reached a record high, with a whopping 27,193 incidents in the months leading up to June - incredibly, there were also 41,103 incidents of self-harm.
It's an issue that has been steadily rising over the past five years, according to the Guardian.
"I don't think you can punish someone and rehabilitate them at the same time and to be honest I didn't see much rehabilitation going on at all," says Ross.
