GUWAHATI, Nov 11: The GST Intelligence and Enforcement Unit continued its investigation into Maa Kamakhya Coke Industries in Beltola here over suspected GST evasion involving several crore rupees.

The search operation, launched at the company's office on November 5 following allegations of fake Input Tax Credit (ITC) claims, entered its seventh day. Investigators seized several documents and electronic devices and continued their examination.

Officials suspected that the firm tried to claim ITC worth several crore rupees through invoices obtained from fake taxpayers.

Notices were issued to the company's three owners — Anil Kumar Agarwal, Bimal Kumar Agarwal and Nabin Kumar Gupta — asking them to appear for the investigation. Gupta cooperated with the team, while Anil Kumar Agarwal and Bimal Kumar Agarwal did not appear despite repeated notices, officials said. They have been summoned again.

Investigators identified more than 10 GST registration numbers linked to the firm and expanded the inquiry to examine transactions and tax records of related business establishments.

The GST department also conducted a separate search at Mahalaxmi Continental, another firm linked to Maa Kamakhya Coke Industries. Gupta was found to have links with the firm, though the nature of suspected irregularities there was not yet clear.

Maa Kamakhya Coke Industries deals in coal trading and coke production. Its office is located at Beltola Tiniali, while its production unit is in Amingaon.

The investigating team was considering seeking assistance from the Enforcement Directorate and the Directorate General of GST Intelligence, if required. Officials said further legal action could follow if tax evasion allegations were established, adding that the allegations remained unproven until the investigation was completed.
