Singh, who is a 1985-batch Maharashtra cadre officer, was prematurely asked to go back to the state cadre by the then CBI director Vijaya Rama Rao. Singh terms the order void, and says Rao did not have the authority to transfer him. His application claims that Rama Rao took the step "due to considerations which were extraneous in nature". These considerations, says the application, seem to have been prompted by Singhs resolve to "unravel the corruption practised and abetted by powerful corporate entities, particularly Reliance Industries, bureaucrats occupying positions at the apex, and senior politicians including two cabinet ministers Satish Sharma and Jagdish Tytler." According to the former CBI sleuth, intensive investigations had revealed that Reliance "in conspiracy with very senior bureaucrats committed frauds in diverse areas and caused losses to the exchequer exceeding Rs 8,000 crore".
