A man arrested Tuesday on suspicion of manslaughter in the death of U.K. professional ice hockey player Adam Johnson was released on bail, the South Yorkshire Police said.

Nottingham Panthers player Adam Johnson, 29, died after his neck was cut by a skate during a game against the Sheffield Steelers.

South Yorkshire Police did not identify the suspect or say why he was released on bail Tuesday. They said the investigation is ongoing.

A spokesperson for the Nottingham Panthers said they could not comment on the investigation.

Johnson was a Minnesota native who played for the Pittsburgh Penguins in the NHL from 2018 to 2020.

After Johnson’s death, the English Ice Hockey Association, which governs the sport below the Elite League, said it would require all players in England to wear neck guards beginning in 2024.
