Additional Sessions Judge Kanwal Jeet Arora sentenced 72-year-old Bangaru, also a former Union minister, holding him guilty of taking the bribe from fake arms dealers to recommend to the Defence Ministry to award them a contract to supply thermal binoculars to the Army.
The court awarded him the prison term, rejecting his plea for leniency and ordered that he be taken in custody to serve the sentence.
The court also imposed a fine of Rs one lakh on Bangaru, who had been caught on camera accepting the money in his chamber in the party headquarters and had to quit as its president shortly after the sting expose which had created a huge political storm.
"Balancing the twin interest of society and that of the convict, I am of the opinion that interest of justice would be met, if the convict is sentenced to undergo rigorous imprisonment for a term of four years and to pay a fine of Rs one lakh for the offence under Section 9 of the Prevention of Corruption Act," the judge said.
