"Witnesses last night described how a teenage birthday party descended into violence and mayhem.
Stunned onlookers in the Carnhill area in Londonderry told how youths attacked police with bottles and stones and how young girls jumped on top of PSNI Land Rovers as the party spiralled out of control.
The violence occurred as the Government unveiled new proposals to tackle underage drinking.
Ministers have stated that parents who allow children to drink in public could be prosecuted, and it could become illegal for under-18s to be regularly found with alcohol.
The trouble in Derry flared when word was spread by youths on their mobile phones and a crowd of up to 200 young people — many of whom had been drinking — came into the estate and congregated near the house where a 17th birthday party was taking place on Friday night.
A fight broke out among some of the teenagers in front of horrified residents, who contacted the police.
But when officers arrived, many in the crowd launched an attack on them with bottles, stones and other missiles. "
