Continuing the probe into the Oct 2 explosion in West Bengal's Burdwan district, the state Criminal Investigation Department (CID) sleuths Thursday interrogated owners of the houses which the militants had rented.While four people, among them two women, have been arrested, the investigators are on the lookout for more suspects, including Kausar, the alleged mastermind, whose sketches have been released.Two suspected militants died and one was injured in the blast in a house in Khagragarh.The CID investigators Wednesday raided three houses in Burdwan's Baburbagh, Mathpara and Badsahi Road that were allegedly rented by Kausar and his associates. Several incriminating documents and a few firearms were recovered from there.A CID team led by Special Superintendent S.R. Mishra visited the three houses during the day and questioned some of the neighbours."We are interrogating Hasan Chowdhury - the Khagragarh house owner - and Azizul Sheikh, the Baburbagh house owner, and several others in this connection. We are hopeful of apprehending Kausar soon," said a CID officer.
With reports that suspected Bangladeshi militants are involved in the incident, the Border Security Force (BSF) has stepped up its vigil along the India-Bangladesh border.Meanwhile, more than 50 activists of the Bharatiya Janata Party were arrested in West Midnapore district for taking out a rally without permission.The BJP has called for marches and rallies across several districts, demanding a probe by the National Investigation Agency (NIA) which the ruling Trinamool Congress has been vehemently opposing."First the administration intentionally denied us the permission and now they have arrested our activists. It's a blatant misuse of power by the state government," said state BJP president Rahul Sinha.
