(BBC) Jurors have been shown CCTV footage said to show the moment two inmates attempted to kill a prison officer.
Brusthom Ziamani, 25, and Baz Hockton, 26, deny trying to kill Neil Trundle in a “terror attack” at HMP Whitemoor, Cambridgeshire, on 9 January.
Prosecutors have said the pair “lured” Mr Trundle to a store cupboard where they launched the assault with makeshift weapons.
Security video appears to show two men pushing an officer through a doorway.
Giving evidence, Mr Trundle told an Old Bailey jury he went to open a store cupboard after the defendants asked him to replace a broken spoon.
