The CBI is searching two premises, one belonging to Amal Bhattacharya and the other to his company Unix Infrastructure Pvt Ltd, in Kolkata in connection with a 2021 ponzi scam case, officials said on Tuesday.

The Central Bureau of Investigation (CBI) had filed a charge-sheet against Bhattacharya and his company in December 2022, and kept its probe open to investigate the larger conspiracy in the case, they said.
