Amritsar, July 6 -- Punjab chief minister Bhagwant Mann on Saturday said exemplary punishment will be ensured for those who had ruined the lives of youth by selling drugs. Addressing a gathering at Guru Nanak Dev University after dedicating roads and libraries worth around Rs.350 crore to residents of the holy city, the chief minister remarked the "jarnails" who had patronised drug trade had been put behind the bars and will pay the price for their sins. He said no one had previously dared to arrest theseaffluent leaders, but now his government had done so, adding that exemplary punishment will be ensured so that "no one ever dared to commit this sin again". The chief minister reiterated that the state government will not remain a silent spectator while smugglers flourished at the cost of victims. On the occasion, he also announced the launch of a massive road network project, covering 19,000 km of link roads, with a total cost of Rs.3,500 crore. He criticised the Union government for withholding Rs.6,000 crore of the state's share in the Rural Development Fund (RDF), asserting that if released, every road in the state could be built. Despite this, he said the state was optimally utilising available funds to improve infrastructure.
