His statement comes after Union home minister Rajnath Singh said that nobody involved in the scandal would be allowed to get away. "Should be commended that we found out that this was happening, the culprits will be punished," Singh said, adding, "no guilty person would be spared and strictest punishment would be given to them," reports India Today.
