Four hard-core extremists of the Communist Party of India (Maoist) were arrested from Sinduartand in Jharkhand's Bokaro district, police said on Wednesday.
Acting on a tip-off, a team of district police and CRPF personnel raided an extremist stronghold on Tuesday night and arrested the four rebels, sub-divisional police officer, Bermo, Ashwini Kumar Sinha said.
Several others managed to escape, he said.
Two of the arrested rebels had been involved in the expansion of the Naxalite network in the district as well as in neighbouring West Bengal.
The team, which was led by Sinha himself, recovered one indigenous pistol, four live cartridges, four Naxal magazines and six hand written Naxal posters.
