The CBI on Monday questioned senior IPS officer Tathagata Basu in connection with the illegal coal trading case the agency is investigating. Basu, who was the SP Hooghly earlier, was asked if he was privy to such rackets operating in the state.
Basu, now a deputy commissioner at Chandannagar Police Commissionerate, arrived at the Nizam Palace office of the agency at 10.30 am. He was questioned till 5 pm as officers tried to put together the missing pieces.
CBI officials had earlier alleged that Anup Maji alias Lala had been running the coal mining racket through the Asansol-Durgapur-Hooghly area.
Officials wanted to know the steps police had taken to prevent the illegal trade in the area. Basu is the first IPS officer to be questioned in the case.
