Chief Superintendent Jo Banks said:
"We are urging witnesses and anyone with information to come forward.
“We understand that there were many young people in attendance at this address at the time who will know important information to help the investigation.
“In particular we would also ask parents and carers of those who attended to speak with their children and to contact us with information.
“This is a fast-moving and complex investigation.
“Officers will be working in partnership with local schools and there will also be an increased police presence in the area in order to provide reassurance.
