The Madhya Pradesh government has said that the culprits responsible for the IPS officer Narendra Kumar's death would not be spared. With the brutal killing of young IPS officer Narendra Kumar evoking strong reactions across the country, the Madhya Pradesh government has said that the culprits responsible for the officer's death would not be spared. The state mining minister has expressed regret over the killing and said that the government will ensure that the officer's killers were punished at the earliest. Narendra Kumar was killed on Thursday when a tractor-trolley, suspected to be laden with illegally-quarried stones, ran over him when he tried to stop it in Madhya Pradesh's Morena district. Meanwhile, Congress leader Digvijaya Singh blamed the state chief minister Shivraj Singh Chauhan for the thriving mining mafia in the state. He condoled the death of the brave officer and reached out to his family. "I covey my heartfelt grievance to the family of young IPS officer and his wife who is in last stage of pregnancy ... my heart goes out to her. She was the circle officer in my district, where I have been MP. She incurred the wrath of BJP MLA and was transferred out of Rajgarh district," the former chief minister of Madhya Pradesh said. Targeting the BJP government in the state, Digvijaya said illegal mining was rampant in Madhya Pradesh and, starting from the chief minister down to the BJP cadres, all were involved. "Morena is known for its sand and stone quarries. Why had this not been auctioned... this needs to be inquired into. I have requested the chief minister to set up a judicial inquiry for my and his tenure and we should go into leases granted under my and Shivraj Singh's tenure," he said. "There is ample evidence to prove that the chief minister's family is involved in the illegal mining. We have got proof that number of people including BJP MLAs, MPs and influential people are involved in mining activity in open connivance of BJP leadership," he said. Digvijay Singh said the state government was losing massive revenue as these quarries were not being auctioned and leased. Lashing out at state home minister Uma Shanker Gupta for his statement that Narendra Kumar's death was an accident, he said: "I profoundly condemn the inhumane statement of the home minister calling it an accident and not a deliberate murder." Janata Dal-United (JD-U) leader Sharad Yadav also called for strict action against the culprits involved in the killing. "I have raised the issue of illegal mining in the state before. Both BJP and Congress leaders are looting the natural resources in the state. The Madhya Pradesh government should take immediate and strict action against the culprits," he said.
