The Central Reserve Police Force on Monday recovered a huge cache of arms and ammunition from the banks of the Brahmaputra near Pandu in the western part of Guwahati.

The recovery has raised suspicion that militants may have been using the Brahmaputra channel to ferry arms and ammunition dodging tight security vigil on land areas.

The police said the CRPF recovered a huge packet of arms and ammunition that was dumped on the river bed near a docked vessel of Assam Inland Water Transport Department after some people alerted them.

The recovery included three universal grenade launchers, three Austria-made grenades, two kilograms of RDX, a kilogram of gun powder, gelatin sticks and detonators. No one was arrested so far. The arms and ammunition dump was found not far away from the Superintendent of Railway Police of the Northeast Frontier Railway.

The police suspected it was the banned United Liberation Front of Asom that was involved in ferrying the arms and ammunition across the river Brahmaputra with an intention to strike terror in the city located on the south bank of Brahmaputra.

Though the security forces engaged in counter-insurgency operations in the state usually maintain tight vigil on all land routes in the state to check movements of militants, the vigil along the course of Brahmaputra River is limited to only occasional patrolling across the channel near Guwahati and few other urban centres of the state.
