In a fresh video message on Instagram, Modi said paper leaks in various examinations have become a major challenge not only for students but also for the Centre and many states. "The Centre and many states have been facing the paper leak problem for several years," he said, adding that the government had been continuously working to establish an efficient examination system. "We will not spare the paper leak gangs, paper leak mafia and those playing with the future of children," the Prime Minister said. "Paper leak incidents will not be allowed to continue unchecked. Our campaign against this menace will continue in future too," Modi said.
