Maoists are researching different kinds of explosives to develop new ones and make them more lethal, while using sophisticated communication devices to evade eavesdropping by security forces, documents seized from the ultras have revealed.
Chief of the Special Task Force of Kolkata Police Rajiv Kumar said they have found some literature from the Maoists on researches being undertaken to make new explosives.
"Documents seized from Maoists show that they have a technical cell which is researching different kinds of explosives to make them more sophisticated and lethal," he told PTI.
However, how far the Maoists are successful is a matter of speculation, he said.
Noting that earlier Maoists used long wire to set off landmine wires which were cumbersome and could be easily located, Kumar said, "Maoists are exploring ways to set off mines through improvised manpack system activated by remote voice control."
The danger posed by explosives activated through wireless devices was that they could be easily hidden making them more lethal, he said.
Asked whether such explosives were being used for the first time in the country, Kumar said, "That we cannot say. But so far, nothing of this sort has been seized particularly in West Bengal."
