CPI(M) today demanded the West Bengal government to issue medical reports of Sudipta Sen, the key accused in the ponzy scheme scam, currently in police custody and claimed that he had already made some 'startling disclosures' in the case.

"Many heads may roll if he (Sudipta Sen) makes further disclosures in his statement to the police. The government should issue medical bulletin about his health in the interest of fair investigations," CPI(M) Politburo member and opposition leader in state assembly Suryakanta Mishra told reporters.

Sen had a medical check-up in a state-run hospital recently. Demanding security of all those arrested in the Saradha chitfund scam and were now in police custody, Mishra alleged that more Trinamool Congress leaders may be found involved in the scam if Sen speaks further and makes more disclosures.
