A school tutor who sexually abused boys more than 100 times was allowed to continue to prey on his pupils despite two complaints against him, victims say. Prolific predator Patrick Sharkey, jailed for six and a half years in June, worked at the County Londonderry school for more than a decade after the complaints and attacked more boys. One of his victims, Eamon McLaughlin, said his parents went to the principal after he was attacked during a weekend in Donegal.
