Groups warn teenagers warned over 'prinking'
More than 100 young people were treated by paramedics for the effects of alcohol and, in some cases drugs, at a concert in Belfast.
It is believed many of them arrived at the venue already drunk.
BBC Newsline's Kevin Sharkey reports on how the incident at Belfast's Odyssey Arena on Thursday night was not a one-off.
