Expressing relief over the release of the abducted policemen by the Maoists, Bihar Chief Minister Nitish Kumar today said such incidents could recur in the state where elections are due later this year and demanded that all polling booths should be manned by central forces. Addressing a press conference in Patna hours after the three policemen were released, Kumar said helicopters should also be deployed for aerial surveillance and the state government would bear the expenses for that. The Chief Minister said he was relieved that the policemen, Abhay Prasad Yadav, Rupesh Kumar Sinha and Ehshan Khan, who were taken hostage on August 29, were freed but regretted that the fourth policeman, Lucas Tete, was killed. The state Director General of police Neelmani told AIR that abducted security men were found in forest areas near Lakhochak village in Lakhisarai district. Apprehending that Maoists might resort to violence, Nitish Kumar said the state police must be spared for law and order work in Bihar during the elections. Renewing his appeal to Maoists to come forward for talks, he appealed to them to shun violence and join the mainstream. In a related development, Prime Minister Dr Manmohan Singh listed the Naxal problem, as one of the top issues that would have a bearing on how India would shape in the years ahead. Talking to editors in New Delhi, he said, though naxalism is one of the greatest security challenge facing country, but there is no quick fix solution to it. He favoured a two-pronged approach of addressing valid economic and social reasons behind the problem and at the same time enforcing law and order.Meanwhile, BJP today welcomed the unconditionalrelease of three abducted Bihar policemen and asked the Centre to implement the integrated plan to tackle the Naxal menace. BJP spokesperson Prakash Javadekar told reporters in New Delhi that the NDA government in Bihar led by Nitish Kumar handled the situation with a strong resolve and took various political parties into confidence. RJD and LJP chiefs Lalu Prasad and Ramvilas Paswan, however, maintained that the hostages had been released on humanitarian grounds and the Nitish Kumar government could not take credit for it. On the other hand JD(U) national president Sharad Yadav slammed the opposition for playing, what he called dirty politics over the release of three Bihar policemen from the captivity of Maoists.
