Siliguri, Sept. 9: Eight months after their camps in the Bhutan jungles were busted by the Royal Bhutan Army, Indian militants have reappeared in Samchi and Saprang districts of the Himalayan kingdom, said a recent report prepared by the BSF.

At least four camps have been set up by the Kamtapur Liberation Organisation-United Liberation Front of Asom-National Democratic Front of Bodoland combine in the two districts, said the report.

According to sources, the camps have been put up at Tading Hills and Tendu in Samchi district, and west Nichula and Gelephu in Saprang district.

Confirming the report, BSF inspector-general of police Sukhjinder Singh Sandhu told The Telegraph: ?We have information that the Ulfa-KLO-NDFB combine is trying to set up new camps inside Samchi and Saprang districts located in the south-western part of Bhutan. Earlier, the camps were scattered across southern Bhutan, bordering Arunachal Pradesh in the east and Sikkim in the west. The actual area was between Daifam in the east and Samtse in the west.?

West of Samchi lies Kalimpong while in the east there is Paro, a district in Bhutan. Saprang is sandwiched between Chhukha and Samdrup Jongkhar, both districts of Bhutan.

Director-general of state police Shyamal Kumar Dutta, who visited Siliguri on Tuesday, also confirmed intelligence inputs that the Indian rebels were in the process of re-grouping in Bhutan and had forged a ?working unity? with the Maoist guerrillas of Nepal.
