Rajeev Kumar took over as the state CID chief after completing his tenure as the city police chief.
The West Bengal government has given additional charge of the state directorate of economic offences and the special task force (STF) of Kolkata Police to former city police commissioner Rajeev Kumar.
Mr Kumar, who recently took over as the state CID chief after completing his tenure as the city police commissioner, would hold additional charge of the two departments until further orders, a home department official said Saturday.
The order was issued by the state home department late Friday evening.
Rajeev Kumar, a 1989-batch IPS officer, had been embroiled in a controversy for being at loggerheads with the CBI over its investigations into the Saradha Chit fund and Rose Valley scams.
A team of CBI officers was stopped from entering the residence of Mr Kumar, the then Kolkata Police Commissioner, on February 3 when they had gone to question him in connection with chit fund scam cases.
The move had prompted Chief Minister Mamata Banerjee to start a sit-in-protest in the heart of the city to protest against "the attack on constitutional norms".
On February 5, the Supreme Court had directed Kumar to appear before the central investigative agency in connection with the matter.
It had also said that no coercive step should be taken against Mr Kumar.
Acting on the top court's order, the CBI had questioned Mr Kumar for five days in Shillong. On February 19, Mr Kumar had been appointed the additional director general of police and inspector general of police in the CID.
The Supreme Court Wednesday directed the CBI Director to file affidavit giving details about the alleged contempt committed by West Bengal police and the then Kolkata Police chief in connection with Saradha chit fund scam cases.
