The Central Bureau of Investigation (CBI) on Monday registered FIR against 13 persons in connection with the Narada sting operation case.
The FIR has been filed against Madan Mitra, Mukul Roy, Saugata Roy besides Sultan Ahmed, Iqbal Ahmed, Kakoli Ghosh, Prasun Banerjee, Shbhendhu Adhikari, Sovan Chatterjee, Subrata Mukherjee, Syed Hussain Meerza, Firhad Hakim and Apurva Poddar .
The CBI had on March 20 registered a preliminary inquiry into the case.
As per sources, the CBI also seized laptop and spy cam used by the Narada News in their sting operation.
The investigative agency also named West Bengal Chief Minister Mamata Banerjee, MPs, police officers and ex-MLA in its preliminary inquiry.
Reacting to the court's order, Mamata said that she will appeal against the court order in a "higher judiciary".
Earlier in April 2016, the court had formed a three-member committee to probe the controversial tapes.
Narada News, led by its editor-in-chief Matthew Samuel, had earlier released three sets of videos of its sting operation, where top TMC leaders were allegedly seen accepting bribes from journalists posing as businessmen.
The ruling party had dismissed the allegation citing that the tapes are 'doctored'.
The sting operation video was released by the portal on March 14, 2016, just ahead of the West Bengal Assembly elections.
