The Central Bureau of Investigation recovered Rs 3.5 crore cash, five kg gold and several incriminating documents during a raid at the Jharkhand’s Principal Commissioner of Income Tax’s house in Kolkata, PTI reported on Wednesday. The investigating agency searched 23 locations in Kolkata and Ranchi, including the house of Principal Commissioner of Income Tax Tapan Kumar Dutta and others, CBI spokesperson RK Gaur said.

A first information report with corruption charges had been filed against Dutta and others, Gaur said, after which searches were conducted in 18 locations in Kolkata and five in Ranchi.

In 2016, Dutta had allegedly conspired with three other Income Tax department officials, Kolkata-based businessmen and entry operators, the spokesperson said. “Dutta allegedly took huge illegal gratification from the businessmen through a chartered accountant to get the income tax assessment files of different assesses transferred from Kolkata/Hazaribagh to Ranchi,” Gaur said.

The CBI has already registered a case against Dutta, Additional Commissioner Income Tax Arvind Kumar, Income Tax Officer Ranjit Kumar Lal, chartered accountant Pawan Maurya and another I-T officer.
