Police have launched a murder investigation after a man died following an assault that caused him to fall off his bike in Oxford.
Eamonn Anderson, 56, was cycling on Oxford High Street at around 11.30pm on 25 October when he was approached by six young men, one of whom kicked him, causing him to fall to the ground.
The group of men then left the scene, police said, and witnesses called an ambulance.
Mr Anderson sustained serious head injuries and died two weeks later at John Radcliffe Hospital.
The senior investigating officer, Detective Chief Inspector Mike Lynch, of Thames Valley Police, said: “This was a violent attack, which initially left the victim with serious head injuries, and has now tragically led to his death.
“We believe this to have been an isolated incident, and since it occurred, we have been in the process of conducting a thorough investigation into it in order to establish the circumstances and also to arrest those responsible.”
“I would like to appeal for anyone who has any information about this assault, to contact us on 101. If you were in this group and have information, please speak to officers.
“Similarly, I would like to appeal for anyone who has might have any footage of the incident to contact us.”
