Murder squad detectives investigating the death of a 30-year-old man in South Yorkshire have said the victim died from a stab wound to the chest.
Officers have named the victim as Zabihullah Rafiq, known as Zabi, who was found early on Sunday just yards from his Sheffield home.
Mr Rafiq had lived in the Bankwood block of flats on Callow Mount in the Gleadless Valley area of the city.
A post mortem examination was conducted on Mr Rafiq's body on Sunday evening.
'Never made it'
Det Supt Andy Thompson said: "Our thoughts are with Zabi's family at this extremely difficult time and we are urging anyone who witnessed what happened to come forward to assist our ongoing murder investigation.
"Zabi worked at Pizza Pronto on Glossop Road opposite the Royal Hallamshire Hospital.
"We know he left there at 0345 BST on Sunday in his silver VW Golf.
"He arrived at Callow Mount, managed to park his car but then never made it through the door, with emergency services called minutes after 0400 BST.
"I want to appeal for anyone in the area at the time, taxi drivers, people returning from a night out or local residents, to come forward with information.
"We're not sure of the motive behind this attack at this stage so any piece of information could be crucial."
House-to-house inquiries are being carried out with detectives also looking at forensics and examining phone data.
