Gas leak forces university evacuation in Coleraine 31 May 2013 Last updated at 16:43 Students and staff have returned to university buildings after a gas leak forced them to evacuate. Six fire appliances were on standby at the site in Coleraine, County Londonderry, after a mains gas pipe was ruptured by a contractor. There are no reports of any injuries and no student exams were disrupted. A spokesperson from the University of Ulster said the evacuation was a "safety precaution." He said the leak was near the campus' Riverside Theatre and emergency services were on site to monitor the situation. Technical personnel from the gas company are expected to repair the leak within three hours. A spokesperson for the fire service said they received a call shortly before 14:30 BST and put a 100 metre cordon up. The A2 Portstewart Road was closed but has now re-opened.
