The Central Bureau of Investigation on Wednesday filed a chargesheet against Krishnarao Bajirao Mahadik, the suspended superintendent of the office of the Director General of Central Excise and Customs (Intelligence), Pune, for allegedly accepting a bribe of over Rs 1.09 crore from two Jalna-based industrialists in 2011.

The others chargesheeted in the case include: industrialists Surendra Pitti, director, S R J Pitti, and Dinesh Bharuka, director, Omsairam Steel and Alloys Pvt Ltd.

The chargesheets were filed before special judge D R Mahajan by inspector N M Parab through special public prosecutors Vivek Saxena and Ayub Pathan.

A search at Mahadik's residence on January 7, 2011, yielded a revolver, Rs 6.37 lakh in cash, 15 kg of silver articles, 250 gm gold jewellery, $800 and 80 files pertaining to purchase of flats. The CBI has described the bribery case as the biggest-ever in the city.

It had received reliable information that a Jalna-based businessman would be coming to Pune to hand over Rs 1 crore to Mahadik to help him evade excise duty.

According to the chargesheet, two businessmen arrived at Kohinoor Estate, near Mariaai gate, in Wakdewadi. Mahadik was arrested while taking over Rs 1.09 crore from Pitti. The two businessmen, Pitti and Bharuka, were arrested later. Investigations have revealed that the industrialists had given the bribe to Mahadik as he had allegedly reduced the actual excise duty of Rs 10 crore to Rs 3.25 crore.

Mahadik, who originally hails from Satara, joined service as an inspector in Ratnagiri.

He became superintendent of central excise and customs in 1997, and joined the Pune office in 2006.

The chargesheet was filed against Krishnarao Mahadik under sections 120 (b) and 204 of the Indian Penal Code and 13 (2) read with 13 (1) (d) and section 7 of the Prevention of Corruption Act.
