Chandigarh, May 31 -- The Chandigarh zonal unit of the Directorate General of GST Intelligence (DGGI) claimed to have busted a network reportedly involved in generating fraudulent Input Tax Credit (ITC) through the issuance of invoices without the actual supply of goods. The mastermind, identified as Manmohan Singh of Ludhiana, has been arrested, it said. GST officials said the fraud involved multiple business entities, including M/s JHA and JHA Enterprises (Delhi), M/s Goyal Trading Agency (Delhi), M/s MAA Vaishno Enterprises (Delhi), M/s SS Enterprises (Ludhiana), M/s PC Techno Solutions (Ludhiana) and M/s PMI Smelting Private Limited (Ludhiana).

An official said that Manmohan has been remanded to judicial custody....
