“I knew the mood had changed when the attacker came through the gates and started attacking one of the the policeman.
“I saw the shine of the blades.”
The former Army staff sergeant, a coach for the British Lionhearts boxing team, said he immediately tried to help but was boxed in by people running in panic – with the brave man jumping over the fence to get to badly injured Keith Palmer.
He said: “It was a fight or flight moment, I just thought ‘these people need help’.”
But Tony, who had been attending Parliament for a press conference, said he feared he had made the wrong decision when he heard a cry “they’ve got knives”.
He said: “I thought maybe I made possibly the wrong decision, that there was an attack by a number (of people).”
He said that the officer who had yelled for people to run had saved countless lives.
Tony Davis has since been recognised for his bravery, given a commendation from St John’s.
