The attack one week ago has sparked days of protests across the country. The victim is recovering from injuries in a New Delhi government hospital but is still in critical condition.
After battling the protesters throughout the day on Saturday, authorities early on Sunday banned their entry into the high-security zone, which also houses the offices of the prime minister and defense, home and external affairs ministries. Police evicted dozens of protesters who had spent the night there.
However, as groups of protesters marched through the streets of New Delhi and began converging on the high-security area on Sunday, authorities withdrew the ban on the assembly of more than five people there. But it set up barricades to keep them away from the president's residence.
Protesters tried to break the police cordon repeatedly by hurling stones and water bottles and pressing against the steel barricades. Policemen responded by firing tear gas and using water cannons against them. The battle continued throughout the day.
