Social media was abuzz with shock about the lynching, following which a clarion call was issued by Gurgaon-based filmmaker Saba Dewan asking people to gather at Delhi's Jantar Mantar for a protest against the targeting of mostly minorities, namely Muslims and Dalits, by self-appointed cow vigilantes.

People converged in various cities, including New Delhi, Mumbai, Kolkata, Lucknow, Kochi, Thiruvananthapuram, Allahabad, Bengaluru and Hyderabad. Here are glimpses from the protests as they happened across the cities.
