A MURDER investigation has been launched after a man who was the victim of an assault died from his injuries.

Jamie Adam Kelly, 30, who was from Leeds and well known in the Rawdon, Yeadon and Guiseley areas of the city, died in hospital on Monday.

The incident happened in Doncaster on Sunday night, South Yorkshire Police said in an appeal for information.

The force urged anyone who could assist with enquiries who has not yet spoken to police to get in touch. 

A spokesperson said many members of the public have already submitted photographs and video footage.

Police said there had been an altercation which left Mr Kelly with serious injuries.

He was given CPR at the scene by officers and then taken to hospital.

In a statement released on Monday night, a force spokesperson said: “At about 9.40pm yesterday, it is reported that a man was ejected from the Vintage Rock Bar on Silver Street where there was a physical altercation with three other men once outside.

“The victim received serious injuries,” said the spokesperson.

A post-mortem was due to take place yesterday.

The spokesperson added: “A 40-year-old man from Worksop, a 26-year-old man from Nottingham and a 33-year-old man from Doncaster have all been further arrested on suspicion of murder after all were arrested on suspicion of Section 18 assault at the scene.
