Volunteers of city-based NGOs and local supporters of social activist Anna Hazare's Jan Lokpal Bill defied prohibitory orders and staged protests outside the Prime Minister's house here on Tuesday.

Additional security has been provided at Manmohan Singh's private bungalow here, as well as to residences of his Cabinet colleagues such as Human Resource Development Minister Kapil Sibal, Parliamentary Affairs Minister Pawan Kumar Bansal and Information and Broadcasting Minister Ambika Soni.

Gaurav Goel and B.S. Makkar, members of an NGO, said people were frustrated with the system and had taken to the streets. “The government should reach a consensus with the Anna team to resolve the issue,” a supporter added.

Several Anna supporters also staged a dharna in front of Mr. Bansal's residence.
