London Ambulance Service said it had a number of resources attending the incident.
Gulled Bulhan, an eye witness said:
“I was crossing the road when I saw a man with a machete & silver canisters on his chest being chased by what I assume was an undercover police officer, as they were in civilian clothing. Then he was shot. I think it was three shots."
