According to the prosecution, Dr C Krishnamurthy and his son Kiruba Sridhar, an MBBS student of a private medical college in Puducherry, colluded with middlemen and officials of Pondicherry University to raise his marks in Ophthalmology.
Failing to clear the paper even after repeated attempts, Sridhar allegedly sought the help of a group that was involved in marksheet tampering. Following the arrest of university officials and middlemen, the case was transferred to the CBI as more names of influential persons were revealed in the preliminary investigation. The father-son duo, however, is yet to be arrested.
