The police are probing why the six came to Kolkata before the Independent Day celebrations. Two of them — Guna Sekharan and Bala Singham are senior leaders of the banned outfit. Police are checking if they came for any operations or for any reconnaissance.
Even the police are interrogating them to find if they had links with Maoists, as there are reports that the Maoists are gradually regrouping in Bengal and have plans to start guerilla warfare in Jungalmahal area of Bengal.
Moreover, the police are also probing if LTTE was supplying arms to the Maoists. (TOI)
