The Bihar Special Task Force on Wednesday arrested eight Maoist extremists, including 5 Nepalis, in Patna after raiding some hotels and a PCO booth.

"We found a large number of documents and literature connected with their activities, Indian currency worth Rs 50,000 and Nepali currency worth Rs 8,000 in their possession," a top STF official told rediff.com.

Some of them, including Maoist Communist Centre (MCC) members from Bihar and Jharkhand, might have escaped before the raids, he added.

All of them were engaged in getting three seriously injured Nepali Maoists treated in a private nursing home in Patna, STF sources said.

In recent months, the Bihar police have arrested nearly a dozen Nepali Maoists undergoing treatment in private clinics in districts adjoining Nepal.

The STF officials are interrogating the arrested Maoists, particularly the Nepalis, to get details about their activities and their links in Bihar and Jharkhand.
