Bengal ministers Firhad Hakim and Subrata Mukherjee were taken to the Central Bureau of Investigation (CBI) office in Kolkata on Monday morning in connection with the probe into the Narada sting operation, news agency ANI reported.

The move by CBI comes after
an earlier sanction tweeted out by West Bengal Governor Jagdeep Dhankhar on May
8, through which the prosecution of Hakim, Mukherjee, Mitra and Chatterjee was
granted to CBI under Article 164 of the constitution.

“Governor accorded sanction
for prosecution of Firhad Hakim, Subrata Mukherjee, Madan Mitra & Sovan
Chatterjee being appointing authority of Ministers @MamataOfficial under
Article 164 & thus competent authority. Media reports that sanction was for
being MLA is incorrect”, the tweet noted.

Later on Monday, Trinamool
Congress MP Kalyan Banerjee, Sobhan Chatterjee’s wife Ratna Chatterjee, as well
as TMC MP Santanu Sen arrived at the CBI office.
