Bundles of currency notes hidden in pipes were recovered in a raid by the Karnataka Anti-Corruption Bureau at the house of an engineer employed with the state’s Public Works Development (PWD).

During the raid at PWD engineer Shantha Gowda Biradar in Kalburgi district Biradar's residence, officials of the anti-corruption bureau recovered Rs 25 lakh in hard cash and a huge quantity of gold.

Video footage recorded during the raid shows ACB officials and a plumber removing sections of pipes and pulling out bundles of notes from inside.

The ACB officials swooped down on the house, acting on a tip-off that the “pipes” meant ostensibly for draining out rain water from the rooftop were actually being used for hiding money that the engineer was making through corrupt means.

The raid at Biradar's residence is part of a statewide crackdown on officials accused of corruption. The Anti-Corruption Bureau has conducted searches at 60 locations on 15 officials accused of corruption and acquiring assets that are disproportionate to their known sources of income.
