Security personnel engaged in anti-Naxalite operation on Sunday stumbled upon 10 landmines and huge quantity of detonators in Orissa’s Sundargarh district, police said.

The seizures were made during a joint combing operation conducted by CRPF, Special Operations Group (SOG) and Orissa Police in different Naxal-infested villages under K Balang police station, they said.

Many residents belonging to Mahupada, Langalakata, Jharbeda, Sanbalijore and Rehlatur villages had taken shelter in K Balang since Thursday after Maoists had issued whip to either support them or face death penalty.

The threat came after the villagers demanded security following an attack on a man by Maoists, suspecting him to be a police informer, in Mahupada village on Thursday.
