PATNA, April 19 -- Bihar's deputy chief ministers, Vijay Kumar Choudhary and Bijendra Prasad Yadav of JD(U), and former chief minister Nitish Kumar's son Nishant Kumar were given Z category security on Saturday. This cover comprises a dedicated team of 22 trained personnel, including four to six specially armed commandos. The state's home department detailed the new security arrangement in a notification issued on Saturday. The notice stated that Shravan Kumar, a former minister and close aide of Nitish, would also receive Y+ security. Meanwhile, the Z+ security detail for former deputy CM and BJP leader Vijay Sinha was downgraded to Z category, according to the notice. Both former deputy CMs, Sinha and Samrat Choudhary, had Z+ protection. Home department officials said the decision followed a review of the beneficiaries' security during a State Security Committee meeting held on Friday. On Saturday, Naveen Kumar, joint secretary of the state government, issued a formal letter to the director general of police (DGP) regarding this. The case of Nishant Kumar is curious, as he is neither a member of a legislative house nor a long-standing politician. However, according to officials, he hails from former CM's family and is now actively participating in his party's political activities, making him a candidate for heightened security cover. Nishant plans to embark on a statewide political tour soon. Former CM Nitish too recently received Z+ security protection, which he will retain as a Rajya Sabha member....
