The still unnamed policeman and amateur rugby player confronted the three knife-wielding terrorists who unleashed carnage in the London Bridge area on Saturday night.
It was reported by the BBC that he remains in critical condition after he was stabbed tackling one of the three attackers.
Met Police Commissioner Cressida Dick praised the “utterly heroic” actions of the officer, who was taken to hospital in a police car.
She added: “It’s hard to pick out individual stories but I am immensely proud of him and what he did.”
