Though minor cracks appeared on the office glasses, nobody was injured in the incident, they said.
Two persons, suspected to be RPI activists, came on a motorcycle and one of them pelted stones at the TV channel's office this afternoon, Deputy Police Commissioner Namdev Chavan said.
Soon, the duo fled from the spot, the officer said.
Police suspect that the accused wanted to damage the property of the channel as it did not pay heed to their party's demand to evict Trivedi.
Last week, Athavale led a morcha of party workers to the location of the 'Bigg Boss' house in Lonavala, demanding removal of Trivedi.
The party objected to Trivedi's participation saying the cartoonist had "hurt the sentiments" of the Dalit community with his cartoons that had "grossly insulted" the national emblem and other constitutional symbols.
