Videos show police officers getting off the bus and fleeing the scene.
Three people were killed when a bus carrying policemen hit their motorcycle on the Chapra-Siwan Highway in Bihar on Wednesday morning.
Disturbing videos show one of the three killed under the bus, in flames, as the bus caught fire after its fuel tank exploded. Policemen can be seen rushing out of the bus and standing at a distance, watching the man burning.
The man was allegedly stuck under the bus with the bike after the collision and was dragged for about 90 metres, during which the fuel tank exploded, burning the man alive.
The bus was returning from the 120th birth anniversary celebrations of political icon Jay Prakash Narayan, an event which was attended by Union Home Minister Amit Shah.
Videos of the accident showed the bus in flames, a burning body under it and two more bodies on the road.
