"We are in the very early stages of our enquiries and we are trying to piece together the circumstances surrounding this stabbing. Officers have spoken to a number of people at the club, but I know there are more people out there who need to tell us what they saw. We are particularly keen to hear where the offenders went next. We are working hard to find those responsible and we will do all we can to bring them to justice."
