Police have named a man who was stabbed to death during a "large scale disturbance" outside a house party.
Emergency services scrambled to a suburb of Sheffield shortly after midnight on Saturday following reports of violence.
Marcus Ramsay, 35, was rushed to hospital with multiple stab wounds to his upper body.
He was pronounced dead shortly after arrival.
Three other men, all aged 24, sustained 'non life threatening' injuries were treated at hospital before being released a short time later.
A post mortem carried out yesterday concluded Mr Ramsay died as a result of a stab wound.
South Yorkshire Police's investigation is ongoing this evening and investigators are still trying to ascertain the exact circumstances surrounding the incident.
They have renewed their appeal for anyone with information to come forward.
Senior investigating officer Detective Chief Inspector Mark Oughton said: "The answers to this investigation lie within the local community.
"I am aware that there were large numbers of people congregated on Horninglow Road due to a house party and I believe that many of them will have seen the altercation that led to Mr Ramsay being fatally injured.
"As we work to piece together exactly what happened and provide answers for Mr Ramsay's family, it's these people who we need to come forward and speak to us.
"I am urging anyone who saw what happened or knows who is responsible, to get in touch.
"Even if you think the piece of information you have is insignificant, it could prove vital to our investigation."
Anyone with information should call 101 or Crimestoppers anonymously on 0800 555111, quoting incident number 18 of August 8, 2020.
