Around 600 people, including members of the Vishwa Hindu Parishad, gathered near a MCD dustbin where the leftover was being dumped.

The officer said the mob has been dispersed.
Police personnel have also been deployed outside a mosque in the area to ensure that no untoward incident happens in the area, said another officer.
