The CBI has accused Akhtar Ali, a former deputy superintendent at RG Kar Medical College and Hospital and an initial whistleblower, of being involved in corruption. The agency alleges Ali manipulated procurement processes for personal gain, receiving financial benefits from vendors. He is accused of changing standard procedures in collusion with others to favor specific vendors, receiving air travel tickets and cash. This development follows a supplementary chargesheet filed by the CBI in a multi-crore financial irregularities case at the hospital.
