Development comes three weeks after the arrest of Trinamool Rajya Sabha MP Srinjoy Bose.

In a major development concerning the ongoing investigation in the multi-crore Saradha scam the Central Bureau of Investigation on Friday arrested West Bengal Transport Minster and senior Trinamool Congress leader Madan Mitra.
Mr. Mitra, perceived to be close to Chief Minister Mamata Banerjee, is an important Minister in her cabinet. He is the first Minister in West Bengal to be arrested by the CBI in the Saradha case
“CBI has arrested Madan Mitra, a Cabinet Minister in the Government of West Bengal on prima facie evidence of criminal conspiracy, cheating and misappropriation as well as deriving undue financial benefits from the Saradha Scam,” a senior official of the CBI told The Hindu.
The arrest comes as a major embarrassment to the West Bengal’s ruling party which had already suffered a battering of its image on account of several of its leaders involved in various Ponzi scams.
The setback comes three weeks after the CBI arrested Trinamool Rajya Sabha MP Srinjoy Bose in the Saradha scam.
Mr . Mitra was earlier summoned by the agency on November 21, 2014. However, since he was admitted to a city hospital the Minister sought exemption from appearing before the CBI.
On Friday, Mr. Mitra appeared before the office of the CBI located at CGO complex in Salt Lake area at around 11 a.m. Though he did not respond to questions by journalists, he appeared disturbed at photographs and videos being taken before entering the CBI office and complained to local police about this. He was reportedly grilled for over three hours prior to his arrest.
Other than allegations of pressurising Saradha chairman and managing director Sudipta Sen, Mr. Mitra has publicly endorsed the Saradha group. In a public gathering, whose recordings are going round in local channels, the Minister is seen heaping praises on Mr. Sen stating that the Saradha chief has shown “how to make an ocean from a drop of water”.
The agency has also arrested retired DGP and Trinamool leader Rajat Majumdar along with three other people — Debabrata Sarkar, Sandhir Agarwal and Sadanand Gogoi — in connection with the Saradha scam.
