In a statement, the Met said the officer was treated at the scene and then taken to hospital by London Ambulance Service, but later died.
No police firearms were discharged, according to the police.
Commissioner Cressida Dick said: "This is a truly shocking incident in which one of our colleagues has lost his life in the most tragic circumstances. My heart goes out to his family, direct colleagues and friends."
