A 23-year-old man died yesterday after being shot in the chest in broad daylight in a Sheffield street.
As police launch a murder investigation and step up patrols in the area where it happened, here's what we know so far.
When and where did it take place?
Police said they were called to Daniel Hill, in Upperthorpe, on Saturday at around 1.35pm
Police said a man was reportedly shot in the chest. He was taken to Northern General Hospital, where he died soon after the shooting.
Some reports have suggested he was in or near to a black Mercedes when he was shot. It is not known if this is true but forensics officers were examining a black Mercedes parked within the police cordon on Saturday evening.
Who was the victim?
The 23-year-old's identity has not been announced by police, but he has been named locally as Aseel. One man, who claimed to be a family friend, said he was well known in Upperthorpe, where he had grown up, but had moved away.
It is understood he was arriving at or leaving a family celebration when he was shot dead.
Has anyone been arrested?
Police have launched a murder investigation, but had not announced any arrests as of Sunday morning, and it is believed the killer remains on the loose.
What was happening at Northern General Hospital on Saturday afternoon?
Visitors to the hospital reported that armed police were present and the entrance to the A&E department was taped off. We are not aware of a separate incident at this stage, so we believe this was a precautionary measure.
Is there any link to a shooting in Shiregreen last Monday?
Another man was shot in the chest in Shiregreen on Monday night. It is not known at this stage whether the two shootings are thought by police to be linked.
The 25-year-old was taken to hospital with life-threatening injuries but his condition was later described as stable. A 24-year-old man was arrested and bailed on suspicion of attempted murder.
Is there a gun problem in Sheffield?
As well as the shooting in Shiregreen, yesterday's killing comes just weeks after shots were fired through the window of a house in Southey Green, narrowly missing a pensioner, in what police said was a case of mistaken identity. The moment those shots were fired was captured in chilling CCTV footage.
That shooting is believed by police to be linked to an almost identical incident in Wortley Green, High Green, the previous month.
