Police said it is believed a car pulled up and an unknown number of people got out before chasing Jarvin and his friend down the street and stabbing them.

They then fled the scene leaving the father-of-three children - all aged under five - dying in the street. Another man, aged 23 and a friend of Jarvin's, was also stabbed and is recovering in hospital. No arrests have been made yet.

At a press conference at South Yorkshire Police's headquarters today, chief superintendent Stuart Barton said: “To the people who did this you have got to come forward and hand yourselves in.

“As a father myself I would urge them to think of the man's family. He had three children, all under the age of five. The family are devastated.”

He added that Jarvin and his friend are from Sheffield but not from the Burngreave area and officers are trying to ascertain why they were there.

The officer said: “We are trying to establish a motive for why they were in the area. It is key that the public responds to this appeal and helps us to piece together what happened.”

He said it was too early to say if the attack was gang related or linked to previous stabbings in Burngreave in recent months but added officers are keeping an open mind.

He said: “We will be making many lines of enquiry, including speaking to people who knew the victim, but it is too early to say what the reasons are behind the attack at this stage.”

The murder weapon has not yet been recovered and a forensic team is expected to be working at the scene over the weekend.

The area has been sealed off since the incident yesterday and is expected to remain in place until tomorrow at least.
