The People's Revolutionary Party of Kangleipak (PREPAK) is a militant group formed by R.K. Tulachandra with a primary base of operations in the northeastern Indian State of Manipur. Before this region was incorporated into the country of India in the early 1970s, it was dominated by three separate ethnic groups: the Naga, Kuki, and Meitei. While these groups still inhabited the area, the rapid immigration of businessmen and laborers from northern India, West Bengal, and East Pakistan (now Bangladesh) during the 1970s upset many in the Meitei population, who felt they were being politically marginalized by the flood of "outsiders" and increased meddling by the Indian government into its historical territory.  Meitei insurgents who returned from the Indo-Pakistan War in 1971 felt that Manipur was being overrun by foreigners, and throughout the decade, several Meitei nationalist groups were formed in opposition to India's governance of the State. PREPAK is one of these groups who have pledged to expel all "outsiders" from the area and establish an independent state of Manipur. <br /><p><br />Tulachandra was killed by government security forces in 1985, and the group was weakened by factional clashes in the area from the late 1980s and into the mid-1990s. By the end of the 1990s, PREPAK was reorganized by Urrikhinbam Sarat and became a well-organized and highly trained force.  The group is believed to have AK-series rifles, sniper rifles, rockets, mortars, and explosives in its weapons caches for use in attacks. PREPAK has a history of targeting civilians (probably those considered "outsiders") in the Manipur region along with government security forces through bombings and small arms assaults. PREPAK frequently works with two other ethnic Meitei groups, the United National Liberation Front (UNLF) and the People's Liberation Army (PLA). These three groups often operate together under the name of the Manipur People's Liberation Front (MPLF).  There is also some evidence to suggest that PREPAK has some connections with Pakistan's Inter Services Intelligence (ISI) agency. One member of PREPAK confessed during an interrogation that the ISI assisted his transport to Afghanistan to receive guerilla training in the late 1990s. However, it is unknown if PREPAK continues to have any active links to ISI.<br />
