One of London's new bendy buses has been destroyed after bursting into flames in central London.
The bus was left a blackened shell
Passengers and the driver escaped without injury when the R436 bus caught fire just north of Marble Arch at 0612 GMT on Wednesday.
Operator London Central was unable to say how many people were on board the bus, which can carry 139 passengers.
Edgware Road was closed in both directions as firefighters tackled the fire.
Colin Farrant, London Central's commercial manager, said: "The cause of the blaze is currently unknown and we are therefore undertaking a joint investigation with the vehicle manufacturers."
The bus had been near the end of its route across the city from New Cross, in south-east London, to Paddington, in west London.
It had been in operation for less than a year and was one of those introduced to ease traffic flows before the congestion charge was introduced.
