7. Police at the scene in Shepperton Road.
10. Shepperton Road resident Rosa Whiteread told the BBC:
I was asleep and I heard shouting – it woke me up.
I looked out of the window and I saw lots of police, there must have been around a dozen of them. I asked them what was going on, but they said they couldn’t tell me. It’s shocking.
11. The death marks the first fatal police shooting in London since 2011, when the killing of Mark Duggan sparked widespread rioting throughout the UK.
The shooting comes a day after an 82-year-old woman was found beheaded in a garden in Edmonton, north London. A 25-year-old man has been arrested in connection to her death.
