"As per the plan of the Maoists' Saranda platoon, about 100 cadres with help from other areas could strike any place in the region," he said.
The arrest was vital as they revealed the Maoist plan on co-ordination among the cadres of Jharkhand, Chhattisgarh and Odisha to strengthen the sagging confidence of the outlawed organisation, Jethwa said. They were nabbed at around 2 am at Lungra Ghati under K Balang police station by a joint team of CRPF and the district volunteer force following a tip off.
Bhuiyan and Horo were accused in the killing of Ajit Bardhan, a sub-inspector of police in 2009, and former woman Maoist Kandri Lohar and her four-year-old son last year. Lohar had left the CPI-Maoist and joined the police as home guard.
They were also allegedly involved in looting Rs 49 lakh from a vehicle on August 6, 2010.
Jethwa said the arrested two were under the active command of Anmol, who coordinated movement of Naxal cadre in Odisha part of Saranda forest.
"Anmol, Sandeep of Deogarh division, and Kunu Dehury, who is heading Sambalpur along with Abhaya and Ajaya from Saranda platoon of guerrilla division of the Maoists, came together and have made a plan to strike soft targets in this part of the state," the DIG said.
The police in all the neighbouring districts like Deogarh, Sambalpur, Angul and Keonjhar have been informed about the possibility of an attack, police sources said.
The police have seized one double barrel country made pistol and ammunition from them.
