Acting on a complaint of bribery from a local builder, ACB sleuths raided Bally Municipality sub-assistant engineer Pronab Adhikary's residence at Malipanchghara of Bali on Friday and recovered bundles of currency notes hidden inside box beds and even the cistern and commode of an unused bathroom and several other places of the house, a senior officer of the unit said on Saturday.

Stacks of currency in denominations Rs 1,000 and Rs 500 and Rs 100 were also unearthed under floor tiles in one of the six rooms in Adhikary's house and from under the floor of the balcony, the sleuth said.

"We had specific complaints against Adhikary accepting bribes on the basis of which the raid was conducted yesterday. And during the raid huge stacks of cash hidden at different places were seized," the officer said.

"Not only cash, gold ornaments worth over Rs 14 lakh, diamonds, innumerable documents of term deposits and fixed deposits were also recovered against which the accused engineer failed to show any supportive documents," he added.

Police also arrested the 50-year-old engineer's son, an engineering student, for attacking an ACB sleuth during the raid and also for allegedly helping his father in taking bribes.

"We had to face lots of trouble from the locals and some of them even attacked one of our officers mistaking us as robbers. Then force from Malipanchghara police station came to our rescue, cordoned off the house and helped us to carry on the raids," the officer said.
