A report from the Catholic Church's own watchdog has found that 870 allegations of child sex abuse were made against members of the Christian Brothers since 1975.
The National Board for Safeguarding Children in the Catholic Church has found that allegations were made against 325 Brothers - 50 of whom are still alive and 12 of whom were convicted.
All of the allegations were reported to the Gardaí and the HSE or Health Boards.
A number of other reports from the board are being published this morning, relating to a number of dioceses.
