Two persons, including an alleged arms supplier to Naxals, were arrested and large quantities of ammunition, explosives and Maoist literature seized from two Sports Utility Vehicles (SUV).

Official sources said, based on specific information, the CRPF 133 Batallion and local police intercepted a Chevrolet Tavera and a Mahindra Bolero bearing Bihar registration two days ago.

On inspection they found bags containing about 403 rounds of ammunitions, explosives and also Potassium Nitrate, a chemical used for making Improvised Explosive Devices (IED).

The personnel also seized a computer CPU, CDs and cassettes from the two vehicles.

The arrested persons were identified as 35-year-old Sanjay Singh, the alleged arms supplier who was travelling along with his wife Vima Minch.

Sources said Singh was earlier arrested by the Jharkhand police in 2008 for Naxal activity but he got bail in January this year.

They added that Singh used to operate in Bihar and Jharkhand and also provided logistical support to the left-wing extremists.
