A victim of a self-confessed paedophile, that BBC News NI has tracked down to Canada, says he was a "monster".

Henry Clarke, 75, confessed to abusing three different boys at care homes in Northern Ireland but has never been brought to justice.

Billy Brown, who was abused by Henry Clarke, says: "You went to bed at night, you pulled your blankets around you as tightly as you could."
