The officer, Suman P.N. of the Walayar GST Enforcement Squad, demanded Rs 4 lakh but was caught accepting Rs 3.5 lakh in a VACB trap.
The bribe was linked to the release of two lorries seized on January 6 while transporting scrap with valid bills.
The complainant reported the matter to VACB after being asked to pay, leading to Suman’s arrest and pending court production.
