Centre carrying out political vendetta: Mamata

She said this while addressing a party meet in Kolkata's iconic Netaji Indoor Stadium on Saturday.

Mamata said, she and her party TMC has been BJP's target because she voiced against communal forces and attended Nehru meet organised by Congress . "I attended Nehru meet, so they arrested our MP Srinjoy Bose."

Attacking BJP she said, "BJP has bought over media. They has decided on vendetta, will fight back politically."

Mamata said, in the last six-months riots have taken place in many states. But there are no reports on that.

WB CM said, "Who is running the CBI? Is it Narendra Modi or is it Amit Shah?"

Wihout naming Modi Mamata attacked PM by saying, so many cases are pending against him.

The TMC chief also targeted media by saying that "journalists are not God." She questioned media's ignorance toward the BJP's election campaign expences.

She also expressed her displeasure over the way centre took away the investigation of Burdwan blast from West Bengal Police to Natioanl Investigation Team (NIA) by saying that "Burdwan blast could have been stage-managed."

Just before Mamata attacked the Centre and BJP over Bose's arrest, West Bengal Governor Keshari Nath Tripathi raised the discomfort levels of Trinamool Congress by saying that the agency must have had some "good reasons" to do it.

"The agency, which has arrested Srinjoy must have good reasons to arrest him. It's premature to make any comments on this issue" Tripathi said on the sidelines of a conference by Murishidabad Heritage Development Society in association with CREDAI Bengal.

Central Bureau of Investigation (CBI) arrested Trinamool Rajya Sabha MP Srinjoy Bose on Friday in connection with the multi-crore Saradha chit-fund scam case.

Bose was arrested after marathon six hours of questioning by the CBI.

Bose, who owns the popular Bengali daily ‘ Sambad Pratidin’, was also the editor of Trinamool's mouthpiece.

It has been learnt that The Rajya Sabha member was allegedly blackmailed jailed Saradha Group chairman Sudipta Sen to extort money from him.

CBI sources said that Bose used to draw a whooping sum of 60 lakhs per month from Sen to run his newspaper firm.

In the letter written to the CBI in April 2013, Saradha chief Sudipta Sen has alleged that Bose “pressurized and extorted” money from him.

Srinjoy also heads Kolkata’s century-old iconic Mohun Bagan Athletic Club.

Earlier in the day when he appeared before the CBI, Bose said that he was called as a witness and will extend all cooperation in the case.

“I have done nothing wrong so why should I be worried,” he told the journalists while entering the CBI office.

Bose is the second MP and third Trinamool Congress leader to be arrested in the multi-crore chit fund scam in which lakhs of people in West Bengal lost their savings.

Suspended Trinamool MP Kunal Ghosh and party vice president Rajat Majumdar were arrested earlier.

Apart from Bose, CBI on Friday quizzed West Bengal state textile minister Shyama Prasad Mukherjee.

Another minister, Madan Mitra, skipped his questioning saying he was in hospital.
