Terrifying moment celebrating students fall from top of moving bus in southern India

This was the moment a group of students dangerously travelling on top of a moving bus fell onto the road as the driver slammed the brakes in southern India.

The students were celebrating ‘Bus Day’ when the incident happened on July 17 in Chennai, Tamil Nadu state.

Footage shows the party-goers falling off the roof of a bus after the driver stopped the vehicle.

At least 20 students have been arrested by Chennai Police following the accident.

Every year students in Chennai celebrate ‘Bus Day’, an event in which students party in buses that ferry them to and from universities.
