A concert has been cancelled due to a "serious threat to public order and safety" after a mass underage drinking binge at an event involving the same DJ.
Police Scotland and the Scottish Ambulance Service also raised concerns about the event following the death of 17-year-old clubber Regane MacColl, who died after taking a tablet known as ''mortal kombat'' at The Arches in Glasgow last weekend.

The City of Edinburgh Council has now suspended the licence for the DJ Hardwell Dance Event at the Royal Highland Showground at Ingliston tomorrow night.
Last night, more than 100 young concert-goers were treated by medics in Belfast as a major incident was declared by the Northern Ireland Ambulance Service and in two of the city's hospitals.
Eighteen people were hospitalised in the wake of last night's incident in and around the Odyssey Arena, where Dutch DJ Hardwell was playing to a crowd of 10,000.
Police said around 300 young people were refused entry to the premises - some of whom were drunk and others too young for the over-16s only gig.
Councillor Gavin Barrie, convener of Edinburgh City Council's regulatory committee, said: "We have taken the difficult decision to suspend the licence on the grounds of a serious threat to public order and safety following advice from Police Scotland and health officials after what happened in Belfast and Glasgow.
"We appreciate the disappointment this will cause to those who were planning to attend the event but protecting public safety must be our priority. Ticket holders should be able to get a full refund."
Hardwell was named the world's number one DJ in the 2013 DJ Mag top 100 DJs poll.
His hits include Spaceman, Three Triangles (Losing My Religion) and Apollo.
Police Scotland Superintendent Matt Richards said: "In response to recent information Police Scotland has received relating to public safety at events held elsewhere in the United Kingdom, the force has expressed its concerns to the City of Edinburgh Council ahead of a proposed concert at the Royal Highland Showground on Saturday 8th February.
"Working with council colleagues, several legal powers have been utilised to ensure that those considering attending the event and wider public are protected. As a result of this partnership approach to harm reduction, a decision has been taken to cancel the event."
