A caretaker who returned to work in a Donegal school where he had previously sexually abused a child and went on to molest and rape four more boys there will be sentenced later this month.
The boys, who were aged between 10 and 17 years old at the time, were sexually abused on an almost weekly basis, some for as long as four years.
The man groomed then by supplying them with alcohol, cigarettes and money.
Two of the boys later told gardai that they were abused by the man in the school after he got them so drunk they were afraid to go home to their parents.
Another said he woke up from a vodka induced sleep to find himself lying naked and with obvious signs of abuse.
The 55-year-old man, who cannot be named to protect the identity of his victims, pleaded guilty at the Central Criminal Court to 38 sample charges which included on dates between July 1st, 1990 and September 31st, 2005.
The man had earlier been convicted in a District Court in Donegal for two incidents of indecent assault at the same school in 1985 and 1986. He was registered as a sex offender and received a six month suspended sentence.
Each of the men, now aged between 24 and 30 years old, stated in victim impact statements before the court that they had turned to alcohol, drug and solvent abuse to escape from the reality of their situation.
