Bharatpur, Oct. 17 -- The prime accused in the murder of former BJP MLA Atar Singh Bhadana was arrested from Bharatpur district on Friday, taking the total number of arrests in the case to six, police said. The accused, Mukesh Gurjar, a resident of Bhonda village under Weir police station limits, is being interrogated to establish his role and identify others involved in the killing. "Police suspect that Mukesh Gurjar played a key role in the murder. He has been arrested and is being interrogated. Six accused have been arrested so far, and efforts are continuing to trace those who are absconding," superintendent of police Rajesh Meena. According to people aware of the matter, Gurjar had launched a sit-in protest around two years ago, with support from villagers, to block access to Bhadana's stone crusher plant. During the prolonged agitation, both sides lodged complaints against each other. Bhadana's brother, Fateh Singh, alleged that a group of villagers attacked the former MLA when he and his wife visited his mining lease site. "My brother and his wife had gone to the site when a group of villagers attacked him with the intention of killing him," Singh alleged. He said Bhadana had operated the mining lease, allotted by the Rajasthan government, for 15 years. "We demand that the state government investigate the murder and take legal action against those responsible for killing my brother," Singh said. Singh also said Bhadana had previously lodged a complaint against people who allegedly damaged machinery at his crusher plant....
