The teenagers who died in Sunday night's incident were Lauren Bullock (17), Connor Currie (16) and Morgan Barnard (17). Lauren passed away at the scene while Connor and Morgan were pronounced dead in hospital. Police have called for any witnesses who have not yet come forward to contact them, even if they are underage. They are not seeking to prosecute anyone under 18 who was trying to get into the licensed premises but say they simply want answers for the families of the victims. CCTV showed that around 400 people were trying to get into the hotel when pushing began and chaos broke out.
