Another stabbing victim, Michael Paffett, said people knocked a catering trolley on to its side to "act like a barrier" and a man threw "a full-size toaster at the guy".

Jurors also listened to the account of football fan Stephen Crean, who was by a door of the buffet car, having just bought a £6 meal deal.

Crean said Williams asked him, "Do you want to die?", as he "pulled out a blade from nowhere".

He said people were "struggling to get the buffet door shut", but when he "heard it click, happy days, then I went towards him [Williams]".

Crean, who was wearing his Nottingham Forest clothing, said he grappled with Williams to "stop him" using the knife, which was "like Come Dancing, we were all over the place".

He said his fingers were cut and Williams was "twisting and turning" the knife.

Crean then managed to call 999 from a locked toilet and said he only came out when he heard police.

Asked about how Williams appeared, Crean said: "100% he was fine, he looked normal, he was just on a mission, he didn't seem angry."
