Indian authorities say riot police in New Delhi fired tear gas Sunday to disperse an angry crowd after a bus crashed into a group of pedestrians, killing seven people.

Police said crowds of angry people blocked streets and beat up the driver of the Blue Line bus.

The privately operated Blue Line buses can often be seen speeding and breaking traffic laws to beat their competitors to pick up passengers. The buses have killed more than 85 people this year.

The Blue Line buses account for about half of the thousands of buses running in the Indian capital.
