A double decker bus hit a pedestrian before crashing into a building in west London.
The pedestrian was injured in the incident before the bus struck the building in Hayes on Friday evening.
Footage shared online appears to show the H98 bus to Hounslow hit the side of the building after apparently losing control as it turned at a roundabout.
The unverified clip shows the bus collide with a car and strike a man walking across the road before crashing.
Police and firefighters attended the scene on Station Road, with crowds gathering around the crash.
First Bus London said there were no passengers on board the bus when it crashed near Hayes and Harlington station at around 7.30pm.
The driver suffered a minor injury and a pedestrian was also treated for minor injuries.
The company said emergency services attended the scene and that damage to the building had been confirmed as non structural.
It said the circumstances surrounding the collision would be fully investigated and that it would support the relevant authorities with their enquiries.
