Serial child abuser John McClean has been jailed for four years for sexually assaulting 22 former students of Terenure College.
McClean, of Casimir Avenue, Harold's Cross, Dublin, abused the boys while teaching English and coaching rugby at the private school in the 1970s, 80s and 90s.
This sentence will begin after he serves a previous sentence for abusing 23 other boys.
That sentence is due to expire in February 2027.
