Police investigating the deaths of three teenagers outside a disco in County Tyrone have arrested two men on suspicion of manslaughter.
One of the men arrested, Michael McElhatton, is the owner of the Greenvale Hotel in Cookstown where the incident happened on Sunday.
The second man being questioned is aged 40.
Lauren Bullock, 17, Morgan Barnard, 17, and 16-year-old Connor Currie, died after a crush outside the hotel.
Up to 400 people were outside the hotel during the crush, police have said.
Officers are examining CCTV footage of the incident and have appealed for any mobile phone footage or photographs of the crush to be passed to the investigators.
They have asked people in possession of images not to publish them online but to upload them to the Major Incident Public Portal.
The hotel was hosting a St Patrick’s Day party on Sunday night and a large group of young people were queuing to get into the disco at about 21:30 GMT.
The emergency services were called to the hotel after reports that several teenagers had been injured in the crush.
The Northern Ireland Ambulance Service declared it a major incident and police, firefighters and environmental health staff also attended the scene.
Officers want to speak to people who were at the hotel at the time and have already tracked down 160 witnesses.
They have reassured anyone who was in the queue that they will not face questions about being under-age at a licensed premises.
After discussions with the director of the Public Prosecution Service, Det Ch Supt Raymond Murray said the PSNI have agreed that age is “not an issue in this investigation”.
“The focus of our investigation… is about trying to find answers for the families of the three teenagers who tragically died.
“We need to know what you saw so the heartbroken families of Connor, Lauren and Morgan know what happened to their children,” he said.
Lauren Bullock was a pupil at St Patrick’s College in Dungannon while Connor and Morgan attended St Patrick’s Academy in the same town.
Support has been offered to young people affected by the tragedy.
Northern Ireland’s Education Authority (EA) has deployed staff from its “critical incident team” in five schools in the area.
EA chairwoman Sharon O’Connor said they have also “provided support and advice to a further seven schools in the area”.
“The EA Youth Service has opened its facilities at Ógras Youth Club, Coalisland, Dungannon Youth Resource Centre and Cookstown Youth Resource Centre in order for young people affected by the tragedy to engage with youth workers,” she added.
