Wearing black shawls, Trinamool MPs protest outside Parliament

Draped in black shawls, Trinamool Congress MPs on Monday staged a protest outside Parliament House against the arrest of West Bengal minister Madan Mitra in the Saradha chit fund case, accusing the Centre of misusing the Central Bureau of Investigation.

Displaying placards with slogans like 'PM, Amit Shah Bengal is angry', members of the Trinamool Congress Parliamentary Party raised slogans.

Some of the MPs also displayed photographs of Sahara group chief Subrata Roy shaking hands with Prime Minister Narendra Modi. Trinamool has alleged that a diary -- detailing financial transactions -- recovered from Roy had the name of Bharatiya Janata Party President Amit Shah. But the BJP had dismissed the allegation.

Trinamool MPs alleged that the CBI was being "misused" to suit the interests of the ruling dispensation at the Centre. The protesting MPs said they would raise the issue in both Houses of Parliament.

Soon after CBI arrested state Sports and Transport Minister Madan Mitra on Friday evening in the Saradha scam, Chief Minister Mamata Banerjee had slammed the ruling BJP at the Centre, Prime Minister Modi and Shah, saying the arrest was "a  conspiracy to destroy democracy in the country".
