Vigilance and Anti-Corruption police seized Rs 4.75 lakh cash from the house of a Backward Class Welfare officer of Theni district in a raid today.
Officials said the officer provided accounts for Rs 2.75 lakh, but could not give a proper explanation for the balance. The raid was carried out following a complaint that he had demanded Rs 13,000 as bribe from a farmer for providing a subsidised loan for digging a well.
DVAC officials laid a trap and gave the farmer Rs 7,500 in chemically treated currency notes, to be handed over to the officer. The man accepted the cash last night, police said.
Officials raided the house today and seized Rs 4.75 lakh, including the bribe money. The man was arrested and remanded to judicial custody.
Police claimed the notes were so well chemically coated that the recipient's fingerprints would not be erased for at least five days. They said this was the first time the department was trying out this technology.
