The Assistant Garda Commissioner, Mr Jim McHugh, has met representatives of some of Leinster's leading fee-paying rugby schools to discuss the incidence of post-match violence between rival pupils.
As part of this, junior Garda liaison officers, who normally work with young offenders, will visit some of the schools to talk to pupils.
The initiatives are in response to the killing of Mr Brian Murphy (18) last August outside a south Dublin night-club. He was kicked to death after a fight broke out between pupils from several leading rugby-playing schools.
After the incident Garda sources said that in recent years there had been a notable rise in clashes between rival fans from leading rugby schools. Underage drinking was cited as a contributory factor.
In a related development, the schools have introduced their own programme to reduce aggressive behaviour among pupils attending matches. Seven of the most prominent have drawn up a new code of conduct for their pupils.
The Leinster Schools rugby competition begins this week, and the new code is designed to ensure that these games pass off peacefully and that fans act in a "sportsmanlike" way towards each other.
The schools which met recently to draw up the code were: Clongowes Wood College, Co Kildare; St Michael's, Ballsbridge, Dublin; St Mary's, Rathmines, Dublin; Terenure College, Dublin; Blackrock College, Dublin; Belvedere College, Dublin; and Newbridge College, Co Kildare.
Father Leonard Moloney, principal of Belvedere College, who also attended the recent meeting with Mr McHugh, told The Irish Times that schools were reacting to the "tragedies of the summer".
He said while there was little violence at matches, aggression and excessive rivalry could create tension between pupils when they encountered each other subsequently.
A file on the death of Brian Murphy, the student killed outside a night-club, is still being considered by the Director of Public Prosecutions.
Four youths were detained by the Garda last September during their investigation. They were later released without charge.
