Police have appealed for anyone who was in attendance at TCs nightclub on Friday night to come forward with information following the fatal stabbing of Joshua Ribera.
It is believed the 18-year-old was attending a fundraising event for Kyle Sheehan, who was stabbed to death last year.
An 18-year-old handed himself into police yesterday and a second man was arrested earlier today on suspicion of murder.
There were a lot of people in attendance at the fundraising event.
I would appeal for anyone who knows anything to come forward. There are still a number of people who haven't been spoken to by police.
A lot of Joshua's friends were at the function and may have vital information about what happened and we urge them to come forward.
