Some 113 of the 120 sixth-year pupils at the High School in Rathgar were suspended on May 18th after an incident on May 4th in which they locked themselves into the sixth-year common room for 55 minutes and played dance music.
There were 2½ days of lessons remaining.
Pretty sure the same thing would have happened to my class when I was in school had we done something so stupid, perhaps due to the fact that the school is a fee paying school the kids thought they'd get away with it so close to the end of the year?
