India’s Bengal Chief Minister Mamata Banerjee’s sit-in protest against the centre entered Day 3 amid a full blown political stand-off that saw a host of opposition leaders extending support to the Trinamool Congress chief.

The Central Bureau of Investigation, whose move to barge into the house of the Kolkata police chief and question him triggered the mega row, went to the Supreme Court, which heard the evidence against Rajeev Kumar on Tuesday.

The CBI has accused Rajeev Kumar of being a ‘potential accused’ in the Saradha and Rose Valley Ponzi schemes — cases he investigated —  and said it was possible that he might have tried to destroy evidence. Rajeev Kumar cannot be arrested, the top court has given the verdict and his questioning will be done in Shillong.

The confrontation was triggered by a CBI team’s attempts to question commissioner of police, Kolkata, Rajeev Kumar in connection with the Saradha chit fund scam on Sunday evening – a move that Banerjee said was out of vendetta.

The CBI approached the Supreme Court saying Kolkata Police commissioner Kumar was a potential accused in the Saradha chit fund scam and claimed the local police could be destroying crucial evidence. The Supreme Court heard the plea of the investigation agency on Tuesday.
