New Delhi: A group of Anna Hazare supporters on Friday protested outside the residence of Congress General Secretary Rahul Gandhi, shouting slogans in favour of the Gandhian and his demand for a strong Lokpal.

Anna supporters have for the past few days picketed houses of MPs, including Finance Minister Pranab Mukherjee and BJP leader L K Advani, after Hazare's campaign managers called on people to protest outside residences of MPs.

They had also protested in front of Prime Minister Manmohan Singh's Race Course Road residence on Thursday.

The protest in front of Gandhi's residence came hours after he broke his silence on the contentious issue of the Lokpal Bill, praising Hazare but strongly advocating adherence to constitutional principles.

The protesters, who raised slogans in support of Hazare and against corruption, were later detained.
