Two 17-year-olds and a 16-year-old have died in Northern Ireland after an apparent crush at a St Patrick's Day disco.
Police are investigating the incident, where scores of revellers apparently tried to get into the a venue in Cookstown on Sunday .
"Our preliminary investigations show there was a crush towards the front door of this hotel, and in that crush people seem to have fallen," Police Service of Northern Ireland Assistant Chief Constable Mark Hamilton said.
"There seemed to be a little bit of struggling going on to get people up off the ground and that might explain also why there was a report of some fighting."
He made a direct appeal for people with footage of the incident to hand it to police, rather than post it on social media.
Mr Hamilton confirmed the three teenagers who died were a 17-year-old girl, a 17-year-old boy and a 16-year-old boy.
A 16-year-old girl is in a stable condition in hospital, while a further two teenagers were treated for injuries they suffered during the incident.
