The Christian Brothers have revealed that they have uncovered files in the Vatican relating to the abuse of schoolboys in Irish institutions.
The files include written accounts about thirty findings of child sex abuse at six schools between the 1930s and 1960s.
Eleven of the cases relate to Artane Industrial School, while the others relate to other schools around the country.
The Christian Brothers say, the files were found by an archivist last year and will now be handed over to the Committee of Inquiry into Child Abuse.
The files relate to Canonical trials - where the Christian Brother leadership carried out 'internal investigations' into thirty allegations of child sex abuse against individual Brothers in Ireland.
Child sex abuse was found to have occurred in all thirty cases.
