A national anti-bullying programme focusing on changing bystander behaviour should be rolled out immediately in Irish schools, a leading expert urges.

Ireland has been found to have one of the highest rates of “sexting” among young people in Europe with at least a quarter of teenagers admitting they send sexually graphic messages.

One-in-seven students have been bullied while at college and a quarter received unwanted sexual attention, research has found.

One in three teens are using websites facilitating video chats with strangers, leaving themselves open to being groomed by paedophiles.
