A man has been arrested on suspicion of manslaughter over the death of ice hockey player Adam Johnson, whose neck was cut during a match.
The Nottingham Panthers player was hit in the neck by a skate during a match against the Sheffield Steelers on 28 October.
The 29-year-old was taken to hospital where he was pronounced dead.
A post-mortem examination confirmed he died as a result of a fatal neck injury, South Yorkshire Police said.
The force said detectives arrested the suspect on Tuesday, adding that he remained in custody.
Det Ch Supt Becs Horsfall, from South Yorkshire Police, said: "We have been carrying out extensive inquiries to piece together the events which led to the loss of Adam in these unprecedented circumstances.
"We have been speaking to highly specialised experts in their field to assist in our inquiries and continue to work closely with the health and safety department at Sheffield City Council, which is supporting our ongoing investigation.
"Adam's death has sent shockwaves through many communities, from our local residents here in Sheffield to ice hockey fans across the world."
She urged members of the public to refrain from "comment and speculation which could hinder" the investigation.
