A CBI team examined Trinamool Congress MP Abhishek Banerjee’s wife Rujira on Tuesday in connection with the coal pilferage case, officials said. Chief Minister Mamata Banerjee visited the residence of her nephew Abhishek in Kolkata minutes before the CBI team arrived there.

The CBI reached Abhishek’s residence just before noon and the examination went on for around an hour, sources said. The team left around 1.15 pm amid a heavy police presence. The agency sought the examination of Rujira to ascertain the details of her bank transactions, suspecting a connection to the proceeds of the illegal coal excavation money, sources said.
