The West Bengal government has given additional charge of the state directorate of economic offences and the police’s special task force (STF) to former Calcutta police commissioner Rajeev Kumar.

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 on Saturday.

The order was issued by the state home department late on Friday evening.

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 Kumar, the then Calcutta 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 dharna 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. It had also said that no coercive step should be taken against Kumar.

Acting on the apex court's order, the CBI had questioned Kumar for five days in Shillong.

On February 19, Kumar had been appointed the additional director general of police and inspector general of police in the CID.

The Supreme Court on Wednesday directed the CBI director to file an affidavit giving details about the alleged contempt committed by West Bengal police and Kumar in connection with Saradha chit fund scam cases.
