Traffic movement was disrupted for over an hour on Biren Roy Road (West) between Behala Chowrasta and Shibrampur on the southern fringes of the city on Friday after residents protested lack of policing following an accident in which a cyclist was injured.
Deepak Jana had fallen off his bicycle at the Raidighi crossing and was hit by a private bus at 9.15am, said police.
The driver managed to flee but a mob damaged the bus and another bus that was behind it.
They also blocked the road demanding better policing. It was lifted at 10.30am.
The injured cyclist was admitted to Vidyasagar Hospital. Doctors said he was stable.
