Midnapore, Dec. 27 :    Midnapore, Dec. 27:  Police arrested eight top-ranking Naxalite leaders from different parts of Belpahari, following a combing operation by security forces, and recovered huge quantities of arms and ammunition from them. The police have also demolished seven camps, in the dense forests of Jhargram subdivision, where the PWG used to provide arms training to its activists. After the murder of CPM leader Sudhir Sardar and a National Volunteer Front jawan in Banspahari, the district administration beefed up security arrangements in Belpahari police station area and intensified combing operations. Alarmed at the growing activities of the People's War Group-Maoist Communist Centre combine in the district, the state government had directed the district administration to crack down on the Naxalites and provide security to the people. A special force consisting of state police, intelligence sleuths, Rapid Action Force jawans and bolstered by specially-trained personnel, was formed to track down Naxalite leaders and curb the activities of the rebels. Working on a tip off, the special force arrested Amiya Kundu, a front ranking PWG leader last week from Bhalukbasa forest. Kundu's interrogation had led to the arrest of other leaders. The investigating officers had also collected information on the whereabouts and future plans of the PWG. The police said Kundu was the brain behind the murder of the CPM leader and had organised several attacks on CPM supporters. The PWG had also planned to kidnap some CPM supporters. The police have recovered from the PWG two diaries containing names and address of some CPM activists. 'It has been established from the documents recovered from them that PWG activists have regular contact with the MCC in Nepal and PWG in Jharkhand,' said a senior district police officer. Last week, security personnel, accompanied by Kundu, raided several areas, including Bhalukbasa, Rajabasa, Taldangra, and Bamundiha in Midnapore district and Mayurjharna, Kankrajhor, and Laljol in Banjura district, where the Naxalites have a strong presence. Seven PWG leaders were arrested during the raids. The police also located seven camps, where PWG activists were imparted training in the use of firearms, explosives, and sharp-edged weapons. The camps were then demolished. 'PWG activists used to bring tribals to the camps either by threatening them or convincing them of better livelihoods. They were then used in attacks on the police and CPM supporters,' said a district police official. District superintendent of police K.C. Meena said 10 police camps had been set up and policemen with sophisticated arms had been posted at different points in the region. Ten more camps would be set up soon, he added.
