People thronged to protest sites such as the Jantar Mantar in New Delhi raised slogans to spread awareness about the Indian government's advances towards censoring the web.
The Indian arm of Anonymous had sent out the call for the demonstrations following a Chennai court's order to Indian Internet providers to block access to a number of file-sharing websites.
Holding banners and raised slogans like, "Raise your voice, save your voice", internet users protested at a number of public places across India.
The venue of the Delhi protests, initially planned at India Gate, had to be shifted to Jantar Mantar after Delhi Police denied permission to the organisers.
