Sonbhadra: A huge cache of ammonium nitrate - widely used as an explosive - was recovered from this Maoist-affected Uttar Pradesh district, police said on Wednesday.
Nearly 80 quintals of the explosive was recovered on Tuesday from a secluded place in Obra town, some 300 km from Lucknow.
"We have no idea how such a huge quantity of the explosive reached Obra," police inspector Seshdhar Pandey told reporters.
"However, taking into account the Maoist movement in certain areas of Sonbhadra, we cannot rule out the involvement of Maoist groups in bringing the explosive for carrying out attacks on policemen. Investigations are on," he added.
