Investigations reveal that distilleries systematically inflated expenses and fabricated bogus purchases, particularly through bottle-making companies, to siphon off over Rs 1,000 crore in unaccounted cash. These funds were then used for kickbacks to secure increased supply orders from TASMAC. ED searches in various premises across many districts of Tamil Nadu for various offences related to TASMAC and its associated entities and people was based on multiple FIRs. TASMAC comes under Senthil Balaji who is minister for excise besides electricity. Balaji is currently out on bail after being arrested by the ED in 2023 in another money laundering case involving jobs in the transport department.

They also found that TASMAC paid over ₹100 crore annually to transporters. Evidence revealed direct communication between distillery companies and senior TASMAC officials, exposing efforts to secure increased indent orders and undue favours.
