The Maharashtra Police suspect “human error” caused the bus accident on the Samruddhi Expressway in Buldhana district in the early hours of Saturday in which 25 passengers were charred to death, an official said.

Contrary to the driver's claim that the private sleeper coach caught fire after hitting a divider following a tyre burst, police believe that he dozed off and lost control of the vehicle, said the official of the state highway police.
