At least six people have been injured and two trapped in a bus crash on a busy high street in south London. Photographs showed the double-decker embedded in the side of a shop on Lavender Hill, near Clapham Junction in Battersea. Police cordoned off the scene and told commuters to avoid the area after the crash.

The bus mounted the pavement and hit the Poggenpohl Kitchen Design Centre at about 7am on Thursday at the start of rush hour. Passengers described a section of the shop’s awning piercing the front windows on the upper deck of the bus. A witness said he saw a trapped woman screaming and that there was “a lot of blood”. More than two hours after the crash fire crews with cutting gear were still trying to rescue two women from the top deck.

Andrew Matthews, 34, of Wandsworth Town, said he was one of about a dozen passengers on the number 77 bus, which was travelling towards London Waterloo: “I noticed the bus drifting. I heard a smash and saw the roof of the shop going through [the bus] from the front left. It went to the fourth or fifth row. I wedged myself in, bracing myself. As soon as the bus came to a stop there was yelling, screaming. I noticed a lady wedged in the front right-hand side. She was screaming for help. There was a lot of blood.”
