Morgan Barnard, 17, Lauren Bullock, 17, and Connor Currie, 16, all tragically died on Sunday when the entrance queue for a teenage disco at the Greenvale Hotel in Cookstown, Co Tyrone turned into a crush of people.

One teenager died at the scene, while the two others died later at the hospital. A number of other teenagers were also injured.

It has been confirmed that two men have been arrested on suspicion of manslaughter in relation to the incident. The two men aged 52 and 40 were detained early on Tuesday. 

The Belfast Telegraph reports that this is the second St. Patrick's Day tragedy to strike the family of 17-year-old Morgan Barnard. SDLP councilor Denise Mullan said: "It's the 17th of March again and it's hit that poor family once again, and the town as well."

"Morgan lost an uncle in a terrible atrocity in Dungannon back in 1976 when the UVF blew up the Hillcrest Bar. My heart goes out to them and the community's heart goes out to them."
