Moreover, BJP workers of Udaipur on 7th and 8th Sep declared in facebook that they are going to attack CPI-M and accordingly the clash erupted. After that BJP burnt / destroyed over 50 CPI-M party offices and 3 media houses. Out of the incidents, Agartala incident where BJP members during a rally led by Rajib Bhattacharjee, Papia Datta, Tinku Roy, Nabadul Banik, Raghu Ladh, Viki Prasad, Kalyani Roy set fire across the city, was fully recorded and no action was taken by police.

5 journalists received injuries on 8th September and 1 journalist received severe injuries in BJP's attack.

Question arises, why do the BJP workers go to the opposition rally to disturb ? Attacks on Manik Sarkar and various MLAs are not new in Tripura. Even cabinet Minister NC Debbarma was attacked under the BJP Govt.
