A man who suffered life-threatening injuries following a street fight has died, police have confirmed.
Officers were called at about 20:30 BST on Saturday to reports of a large group fighting on Knoll Close in Stocksbridge, Sheffield, with one person reportedly being in possession of a knife.
A 34-year-old, who had been arrested before he was taken to hospital, died on Monday, South Yorkshire Police said.
The force said a post-mortem examination had come back as unascertained pending further enquiries.
Four people were arrested on suspicion of attempted murder following the brawl.
A woman aged 35, and man, 37, were arrested at the weekend, and two men both aged 30 were also taken into custody on Monday.
One of the younger men was also arrested on suspicion of perverting the course of justice.
Police said all four had been bailed pending further enquiries.
Det Insp Adam Watkinson said it was evident from CCTV at the scene that there were members of the public who may have seen the disturbance.
He said: "If this was you, you could hold vital information that would prove pivotal in our investigation."
He urged witnesses to contact the police.
