Around 40 people came to the venue and started shouting slogans against Hazare and his associate Arvind Kejriwal as soon as the 75-year-old activist climbed the stage to begin his dharna.
This led to a minor scuffle between the protestors and Team Anna volunteers forcing them to remove the latter from the venue.
Team Anna member Kumar Viswas claimed that the protestors said, "Anna ko dhakka dedo, Arvind ko maro (push Anna, beat Arvind)" and added that he has an audio recording of the sloganeering by the activists.
Team Anna today launched their indefinite fast at the venue, raising the pitch against the UPA government on the issue of corruption.
Mr Hazare's three close aides -- Arvind Kejriwal, Manish Sisodia and Gopal Rai -- sat on a hunger strike at Jantar Mantar while the social activist is on a dharna.
Mr Hazare has served an ultimatum to the government asking for a decision on their demands in the next four days or else he will join his colleagues on fast from Sunday.
