Twelve suspected Maoists militants were arrested in southern Orissa's Gajapati district after a joint operation by the police and paramilitary troops, police said on Monday.
"We have also seized guns and explosives, Maoists uniforms, money receipts, leaflets and books based on Maoism," said a senior police official. The Maoists were arrested on Sunday and produced in the local court, he said.
Eleven of the arrested guerrillas were allegedly involved in the Ramgiri Udayagiri incident, a sub-division of the Gajapati district in March this year, where nearly 200 armed guerrillas stormed a jail, attacked the town police station, looted a government treasury and freed more than 40 prisoners.
The number of Maoists rebels and their supporters arrested during last two months in the district has gone up to 27, the official said.
On Saturday, three suspected Maoists guerrillas were arrested from a weekly market at Ramjodi in Orissa's western district of Sundargarh.
