Four people have been injured after a double-decker bus had its roof ripped off in central London.
The bus is believed to have hit a tree on Monday morning in a busy shopping street through Holborn.
Three passengers and a motorist were hurt as the roof sheared off and was left lying in the road.
Immediately, pictures of the scene in Kingsway were posted on Twitter.
The bus was a number 91, which runs between Crouch End and Trafalgar Square.
