A 23-year-old man who was arrested on suspicion of murder has been released under investigation.

"The perpetrators need to be found and the firearm taken off the streets," he added.
He appealed for anyone who was in the area or anyone with footage, including from a dashcam, related to the shooting to come forward.
"Equally, if you were a witness and are yet to come forward, I would urge you to get in touch," Det Ch Insp Healy said.
