"(The assault is) a dangerous sign for parliamentary democracy and comes at a time when opposition parties are facing attacks by Trinamool Congress over filing nominations for the panchayat polls," said WBPCC president Pradip Bhattacharya.
"The attack is aimed at hiding (the) misdeeds of the Trinamool Congress," he alleged.
Three lensmen for local TV channels were attacked with iron rods and sticks in Barrackpore by a mob carrying Trinamool Congress flags.
Police said three persons have been arrested in connection with the attack on the lensmen.
