After a Central Bureau of Investigation (CBI) notice in connection to a coal scam case, Trinamool Congress leader Abhishek Banerjee's wife Rujira Banerjee on Monday replied to the agency, asking officials to visit her residence between 11 am and 3 pm on Tuesday. "Though I am unaware of the reason for me being called for questioning or the subject matter of the investigation, you may visit my residence, as per your convenience between 11 am and 3 pm tomorrow, i.e., 23 February 2021," wrote Rujira in a letter to the CBI. "You are requested to kindly inform me your schedule," she added. Earlier on Sunday, CBI served a notice to Rujira Banerjee Naroola, the wife of West Bengal CM Mamata Banerjee's nephew Abhishek asking her to join the investigation related to the coal scam case.
