Security footage from a bus which crashed into a river in China has revealed that the driver was fighting with a passenger moments earlier.
The bus plunged 50m (164ft) off a bridge into the Yangtze River in Chongqing on Sunday – at least 13 people died and two more are missing.
Early reports said the bus had swerved to avoid an oncoming vehicle.
But the new footage shows the driver was being hit by a passenger at the time and struck back, losing control.
Police have said the fight was the cause of the crash, state newspaper China Daily reports.
Passengers can be heard screaming in the disturbing footage, shared by Chinese state media.
Police said the passenger, identified as a 48-year-old woman with the surname Liu, was angry that the bus had missed her stop.
They said she hit the driver, named Ran, with her mobile phone when he refused to stop and let her off.
Witnesses had said they saw the bus swerve across to the wrong side of the road before crashing through a safety barrier in Wanzhou district.
A huge rescue operation was mounted with teams of divers and dozens of boats and cranes deployed. But there have been no reports of survivors.
The wreckage of the bus was pulled out of the river from a depth of 71m on Wednesday night. Several of the passengers’ bodies had to be retrieved by divers.
