Leader of Opposition in the Legislative Council Vinod Tawde has written to Prime Minister Manmohan Singh and Union Home Minister P Chidambaram saying that transferring the officer at a time when investigations in the case are still on is "inappropriate and should be stopped".
Singh, a 1985 batch IPS officer of Kerala cadre, was shifted from the anti-corruption branch of the agency to the economic offences wing on Thursday, a day after the CBI filed its first chargesheet in the Adarsh scam against 13 accused including former Maharashtra chief minister Ashok Chavan.
Though the CBI has maintained that it is a routine transfer, Tawde's letter seeks to question the timing of the move.
Keshav Kumar, a 1986 batch IPS officer from Gujarat cadre, will take over from Singh.
