A teenage girl has died after 'becoming unwell' at a music festival in Belfast over the weekend.

Police have launched a probe into the sudden death of a girl - in her late teens - at the Emerge dance music festival, which was held at Boucher Playing Fields in the south of the Northern Ireland capital.

More than 70 acts performed over Saturday and Sunday, including Fatboy Slim and Bicep - the electronic DJ duo who hail from Belfast. 

But the event - billed as Ireland's biggest electronic music festival - has been overshadowed by the death of the festivalgoer who died in hospital after becoming unwell on Sunday. 

Two other people remain in hospital after also becoming ill at the event.

A woman aged in her 30s is in a serious but stable condition, while a boy aged in his teens received treatment and is expected to make a full recovery, police said.

Belfast councillor Micky Murray described the death of the girl as 'heartbreaking'.

He wrote: 'Heartbreaking news this afternoon of the death of a teenage girl who attended Emerge last night, and two others in hospital.

'I have some very serious concerns about this, and as a BCC asset, I'm requesting an urgent meeting w/ Council officers and Emerge reps.'

A spokesman for the PSNI told the Mail: 'Police attended a report of the sudden death of a girl aged in her late teens on Sunday, 24th August, who died in hospital after becoming unwell at an event in south Belfast. 

'Additionally, two people remain in hospital after taking ill at the same event.

'A woman aged in her 30s is in a serious but stable condition at this time, while a boy aged in his teens received treatment and is expected to make a full recovery. 

'Inquiries into the circumstances surrounding all reports are ongoing.' 

The Emerge festival has been contacted for comment.
