Kolkata special task force had arrested six Sri Lankan men suspected to be members of the banned terrorist outfit LTTE.
All the six LTTE men arrested from Kolkata are Sri Lankan Tamils and they have come to Kolkata four days ago from Chennai.
The police are probing why the six came to Kolkata before the Independent Day celebrations.
According to the police, two of them – Guna Sekharan and BalaSingham are senior leaders of the banned outfit.
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.
