Detectives have launched a renewed appeal to find the gun that was used to kill Leeds teenager Raheem Wilks.
The 19-year-old was shot in the chest at Too Sharps barber shop in Gathorne Terrace, Harehills, on the afternoon of Thursday January 26 last year.
West Yorkshire Police believe it was a targeted attack linked to the supply of Class A drugs in the area.
It's hoped finding the murder weapon will lead to those involved in the wider planning of the shooting being caught.
Three men - Keal Richards, 21, of Francis Street, Chapeltown, Jaydn Manners, 24, of Louis Street, Chapeltown, and Tremaine Wisdom, 29, of Stainbeck Road, Meanwood - were convicted of his murder and given life sentences each with a minimum jail term of 33 years last year.
Firearms experts believe the gun was a Russian-made Baikal Makarov 9mm pistol or similar, which it is thought was used in a gang-related incident in Chapeltown Road on May 25 2016.
In an appeal aired on the BBC's Crimewatch Roadshow today, Crimestoppers announced it would offer a reward of up to £5,000 for information that leads to the recovery of the weapon and the arrest and conviction of those connected to it.
Anyone with information that may aid police should call 101 or Crimestoppers anonymously on 0800 555111.
