A man broke a prison officer's jaw after he was told to remove his flip flops, a court heard.
Rory Payne, 26, was serving a six year sentence in custody at HMP Risley, Warrington, for possession of a firearm when the attack took place.
At Liverpool Crown Court on Friday, Chris Taylor, prosecuting, detailed that on January 5, 2022, at around 9.15am, Payne tried to enter a room in the prison while wearing flip flops. He was told by prison officer Vincent Shanahan that he had to change into trainers before going into that room, as per prison rules.
