TMC Supremo and ex-West Bengal CM Mamata Banerjee’s nephew Abhishek Banerjee was questioned by the West Bengal CID for nearly six hours on Thursday (11th June) in connection with the signature forgery case over the party’s choice of Leader of Opposition in the state assembly.
According to reports, Banerjee arrived at the West Bengal CID headquarters around 5.50 pm on Thursday after obtaining protection from arrest from the Calcutta High Court for three weeks. He left the office at around 11.30 pm. Banerjee appeared before the CID after skipping three earlier summons issued by the investigating agency, citing illness and the filing of a challenge petition before the high court.

Granting him protection from arrest, Justice Kaushik Chandra told Banerjee to appear before the CID at 6 pm on Thursday after returning from Delhi and cooperate with the agency. “This court is of the view that for securing documents the investigating agency is at liberty to do search and seizure as per law… (but) the agency shall not take coercive steps (against Banerjee) for two weeks. If further interrogation is required, the agency will give a 24-hour notice,” the High Court said. Notably, Banerjee had been holding meetings with INDIA bloc leaders, including Rahul Gandhi, in Delhi for the past three days.
Earlier on Tuesday, the CID conducted simultaneous raids at TMC’s central office at party supremo Mamata Banerjee’s Kalighat residence and at Abhishek’s Camac Street office in the city. The raids were conducted to recover the original copy of the TMC’s meeting resolution book and attendance sheet containing signatures of 70 MLAs who attended the party meeting on 6th May. However, the agency did not find the documents during the raids.
The case relates to the allegations of a resolution for the selection of TMC MLA, Sovandeb Chattopadhyay, as Leader of Opposition, containing forged signatures of some TMC MLAs. The proposal was drafted at a meeting held at Mamata Banerjee’s home. The issue was flagged by two TMC MLAs, Ritabrata Banerjee and Sandipan Saha, who called the resolution “manufactured and fabricated”. They said that 14 out of the 70 signatures on the resolution were forged.
This led to the filing of a case and an investigation by the CID. Ritabrata Banerjee and Sandipan Saha were later expelled by the TMC for ‘anti-party activities’.
