East Lothian Courier . Drink has been blamed for a near riot by Tranent teenagers after a junior disco at the Loch Centre had to be stopped. Now steps are to be taken to increase security and make sure youngsters on drink or drugs are kept out of discos. The decision was taken after police reported that the majority of children involved in the February 9 disturbance had been drinking before they rampaged through the streets of Tranent, causing £2,000 worth of damage, when the disco was cancelled after fighting broke out. Community PC John Penman was the first officer on the scene and told councillors at Tuesday’s community council meeting that he could smell drink from teenagers who were causing trouble.
