The Enforcement Directorate (ED) on Thursday interrogated Trinamool Congress MP Abhishek Banerjee’s wife Rujira Narula Banerjee at its Kolkata office in connection with the probe into the multi-crore rupees coal pilferage scam, an official said.

Rujira Banerjee went to the ED office at the CGO complex at around 11 am carrying her son in her arms.

Four officials, two of them women, are questioning her, the official said.

“We are grilling her about a few transactions made in a bank account in Bangkok. Her answers are being tallied with those given by people who were interrogated earlier in the same case,” he said when contacted.

Abhishek Banerjee is the nephew of West Bengal Chief Minister Mamata Banerjee. The Supreme Court has allowed the ED to quiz Mr Banerjee and his wife in the coal smuggling case in Kolkata by giving them an advance 24 hour notice.

The ED had expressed apprehensions at the Supreme Court citing past instances of violence against CBI officers, who were gheraoed in the city after three heavyweight Trinamool leaders were summoned by them in connection with another scam at its office.

It had mailed to the state police seeking protection. Following it, a huge police arrangement was made at the ED office in Kolkata, a senior official of the force said.

The investigation is linked to an FIR filed by CBI in 2020 in a multi-crore rupees pilferage scam.

CBI has so far questioned Rujira Banerjee twice in connection with the scam. The central agency had last year too interrogated her sister Menoka Gambhir, her husband and father-in-law in connection with the probe.

It is alleged that illegal mining of coal was carried out at leasehold mines of Eastern Coalfields’ in Kunustoria and Kajora areas near Asansol in West Bengal. Investigations have hinted towards financial transactions of ₹ 1,300 crore, the bulk of which went to several influential people as per CBI.

The probe revealed that the money was deposited in foreign bank accounts of these influential people through hawala.
