DJ Hardwell gig to go ahead in Edinburgh's Ingliston
A DJ Hardwell gig in Edinburgh is to go ahead later.
The original date in February was cancelled after problems during a performance in Belfast.
There, 100 youngsters were treated by paramedics and the emergency services declared a "major incident" in February as they dealt with the effects of alcohol and in some cases drugs.
Now the police and Edinburgh City Council have stepped up security measures so the concert can go ahead.
The Royal Highland Centre in Ingliston concert for 11,000 fans will run from 18:00 until 04:00.
High-visibility uniformed police patrols will be carried out in and around the venue during the gig and a number of plain-clothed officers will also be at the venue.
People will be searched before they enter and specialist drug detection dogs will be deployed throughout the queues.
There will be a private ambulance service and a safe zone bus for medical treatment.
Ch Insp Graham McInarlin said: "Our message for tonight is clear - we want everyone to have a great night and enjoy the music and carnival atmosphere but to ensure they do not behave in a manner which puts themselves or others in danger.
"We will have large numbers of officers and other resources in place at the event to assist stewarding staff who will be on the lookout for anyone trying to bring drugs, alcohol or weapons into the event.
'Keep people safe'
"If you are found to be in possession of any illegal or dangerous items, they will be seized; you will be refused entry and may face arrest."
He said the organisers had included the terms of admission on their website and the ticket and he urged people to ensure they were familiar with these before arriving at the gig.
"Police Scotland has a wealth of experience in policing large events and have worked closely with our partner agencies to ensure we keep people safe tonight," he added.
"We would ask those in attendance to work with us so the concert is a safe and enjoyable event for everyone."
An Edinburgh City Council spokesman said: "No concerns were raised by partner agencies and, as the applicant met all the licensing requirements, a licence was granted."
