The man, who wore an “I am Anna" T-shirt, was then seized by the security personnel at Parliament.
“The person who demonstrated at Parliament bringing bad name to Anna movement should be taken into custody," said Justice Santosh Hegde slamming the behaviour.
Anna Hazare whose fast has now entered the eleventh day is on an indefinite strike since Aug 16 fighting for a strong Lokpal Bill at the Ramlila Maidan.
The Gandhian crusader is definitely proving a tough nut for the government to crack as he is adamant that he will continue his fast until the Lokpal Bill is passed in the Parliament.
Meanwhile, the veteran apologised to the Prime Minister Manmohan Singh if ever he used harsh words against him.
Many leaders have come together to wheedle Anna to call off his fast. Prime Minister's efforts also went in vain as Anna remains deterrent to scrub up his fight against corruption.
