Hundreds of people gathered in outer Delhi's Mianwali Nagar after rumours spread that the leftover of slaughtered animals being disposed off after Eid ul-Adha were of cows, following which security was tightened in the area, the police said.
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.
