Central Bureau of Investigation submitted its first chargesheet in a Kolkata sessions court on Wednesday, the 90th day of the agency's taking over the Saradha scam probe.

CBI named Saradha group chief executive officer Sudipta Sen, group director Debjani Mukherjee and the company's media chief Kunal Ghosh in the chargesheet and also mentioned five companies of Saradha.

The accused were charged under Indian Penal Code sections -- 409 (criminal breach of trust by public servant, or by banker, merchant or agent), 420 (cheating) and 120B (punishment of criminal conspiracy).

According to sources, the central investigating agency will file a supplementary chargesheet soon that is likely to include names of a few political heavyweights.
