The killer of a young dad from Sheffield is still on the loose nearly six months after he was stabbed to death in broad daylight.
Jarvin Blake, aged 22 and from Gleadless, was knifed in his chest at the junction of Catherine Street and Brackley Street, Burngreave, on Thursday, March 8.
Detectives have never revealed the suspected motive for the attack but are treating the stabbing as targeted.
Four arrests have been made so far over the murder but nobody has yet been charged.
The suspects, three men from Sheffield and one from Rotherham, were released under investigation after being held on suspicion of murder.
Jarvin, who had three children under the age of five when he died, was stabbed after he was chased by a group of men who pulled up in a car and jumped out.
Jarvin's friend, Declan Maw, 23, was also assaulted but survived the attack and was moved to a police safe house.
During a recent hearing at Derby Crown Court it emerged that Maw was a drug dealer.
Last September he was caught dealing heroin and cocaine through a car window in the car park of a Travelodge in Brimington Road, Chesterfield.
Police officers swooped and found 39 wraps of heroin and 38 cocaine deals, worth around £800, in the car.
Maw pleaded guilty to possession of drugs with intent to supply and his sentence was deferred for six months.
