Three 18-year-olds and a 19-year-old are due to be questioned over a stabbing at Uberra in Wolverhampton.
Four teenagers have been arrested on suspicion of murder over a stabbing at a Wolverhampton nightclub.
Thomas Kirwan, 23 and from Oxley, died at New Cross Hospital after being attacked outside the Uberra Club on Saturday, 8th July.
Three 18-year-olds and one 19-year-old were arrested this morning, all in the Wolverhampton area.
Meanwhile officers continue to trawl through CCTV footage from inside and outside the Uberra Club where Thomas was stabbed, after trouble inside the venue spilled outside.
Last weekend police handed out leaflets in the main clubs and bars in the city, a week on from the incident, to appeal for witnesses to come forward, as the club remained closed.
Detective Inspector Warren Hines, who is leading the investigation, said: “We are still piecing together the circumstances of the disorder outside the club that night and continue to examine CCTV footage, which shows a number of people we would like to speak to.
“I would urge anyone who was at the scene of the disturbance to come forward and speak to us.”
Anyone with information should contact Force CID on 101 or the independent charity Crimestoppers anonymously on 0800 555 111.
