"As per Action Taken Report of the Returning Office of Jamuria Assembly Constituency, Flying Squad team of the poll panel inquired into the complaint and removed flex boards from three places under the same constituency," the EC officials said.
TMC national spokesperson Derek O'Brien said the flex boards were an example of defamatory election propaganda by CPI(M) candidate Jahanara Khan.
"It is also violation of the model code of conduct and deserves steps by the poll panel," he said.
EC officials said that the matter has been disposed off with immediate action on March 31, the same day on which the complaint was lodged through the EC's mobile app 'Samadhan'.
