Police immediately intervened and forced away the activists from the spot.
"We protested against Agnivesh for his recent remarks against Lord Shiva. We would not spare anyone, specially those wearing saffron robes, for acting in such a manner," Sanskriti Bachao Manch's convener Chandra Shekhar Tiwari told reporters.
The Manch activists forcibly removed a cloth worn by Agnivesh and also tried to remove his headgear but could not, he admitted.
Tiwari said the people of this country look upon those wearing saffron robes with great respect and if such persons engage in loose talk about gods, then it would not be tolerated.
Later talking to reporters, Agnivesh said that he had pardoned those who were involved in the incident and that he would not like to comment on it.
