Calcutta, Feb. 17: The CBI is likely to file a supplementary chargesheet in the Saradha Realty case this week naming for the first time five persons, including Madan Mitra and Srinjoy Bose.

The five will be charged with cheating, criminal breach of trust, criminal breach of trust by a public servant and misappropriation of funds.

Besides transport minister Mitra and Bose, who quit Trinamul after being granted bail earlier this month and expressed his wish to step down as MP, the others to be named in the supplementary chargesheet are Saradha chief Sudipta Sen's mentor Shibnarayan Das, Sen's lawyer Naresh Bhalodia and suspended Trimamul MP Kunal Ghosh.

'We are in the process of finalising the supplementary chargesheet and hope to file it by this week,' a senior CBI officer said.

The Telegraph had reported in January that the CBI was gearing up to file the supplementary chargesheet against Mitra and the others by February.

Sources said the CBI was running against time to file the chargesheet as some of the accused in the case, including Bose and Trinamul vice-president Rajat Majumdar, had obtained bail.

Lawyers representing Mitra, who will be completing 90 days in custody on February 20, have already filed a bail plea in Calcutta High Court. The appeal has been listed for hearing before the division bench of Justices Subhra Kamal Mukherjee and Indrajit Chatterjee. The same bench gave bail to Majumdar yesterday. Today, the bail plea of another Saradha Realty accused, businessman Sandhir Agarwal, was filed before the same bench.

'Naming someone in the supplementary chargesheet doesn't mean he can be held back in custody. But failure to do so gives the advantage to lawyers seeking bail for the accused,' a CBI lawyer said.

The CBI sources said two pieces of evidence against Mitra would be mentioned in the supplementary chargesheet.

First, the minister's alleged visit to Saradha Gardens, Saradha Realty's biggest project, after he was elected as the MLA of Bishnupur West in South 24-Parganas in the 2009 bypolls.

Second, Mitra addressing a gathering of Saradha agents at a programme in Netaji Indoor Stadium in 2010. Saradha chief Sen was present at the programme.

'Mitra was not so naive not to understand the implication of his visit to the Saradha project site or his addressing agents of the company,' a senior CBI officer said. 'All these point to the larger conspiracy behind the scam.'

The chargesheet is going to mention how Saradha Realty mopped up Rs 397 crore from the market in 2010 and 2011.

While submitting the chargesheet, the CBI is likely to appeal for the custodial trial of Mitra and the four others.

In November 2014, the CBI had submitted its first chargesheet in the Saradha Realty case, naming Sen, his close aide Debjani Mukherjee and Trinamul vice-president Majumdar. Businessmen Sajjan and Sandhir Agarwal, East Bengal club official Debabrata Sarkar and Assamese singer-filmmaker Sadananda Gogoi also featured in that chargesheet.
