The incident took place late this evening in the Civil Lines police station area when an advocate, while returning home from the court on his motorcycle, got hit from behind by a car and died on the spot, police said.
As the news spread, a number of advocates arrived at the site of the mishap where they started pelting motorists with stones, blocking traffic during the busy hour.
Later, while the advocates had assembled at the police station for lodging an FIR, tempers flared up again and they began shouting slogans and vandalising furniture before being pacified by the policemen on duty.
A case was registered in connection with the accident and a search was on for the vehicle which had run over the lawyer, police said, adding that no case had been registered against the agitating lawyers so far.
