Police in the North have concluded that 619 people were in the queue or car park on the night of the crush at a disco in Cookstown.

Three teenagers lost their lives as a result of the incident outside the Greenvale Hotel in Cookstown on Sunday.

The PSNI is refusing to apologise for arresting the owner of a Cookstown hotel on suspicion of possessing drugs with the intent to supply.

Two men, one aged 52 and the second in his 40s, are still being questioned by police in the North after three teenagers died outside a St.Patrick's night disco in Co. Tyrone.

Police and prosecutors made the pledge in an effort to get more teenagers to come forward to speak to officers about the tragedy.
