The natural father of a boy trapped in an old coal bunker by his mother and step-father, has told ITV News Granada that he feels guilty because he was not there to stop it:
It was horrible to think that someone had done that to my son. It was horrible. I would never do it to an animal, let alone a child.
I feel guilty because I wasn't there to prevent it.
Conditions in prison cells are far better than the way my son had been kept and for his age, to be treated like this, it's just despicable.
