In 1972, frail and broken Majumdar died of multiple diseases in police custody presumably as a result of torture; his death accelerated the fragmentation of the movement. After his death a series of splits took place during the major part of the 1970s. The naxalite movement suffered a period of extremely harsh repression that rivalled the Dirty Wars of South America at the same time that the movement got all more fragmented. After Majumdar's death the CPI (ML) central committee split into pro- and anti-Majumdar factions. In December 1972 the Central Committee of the pro-Charu Majumdar CPI (ML) led by Sharma and Mahadev Mukherjee adopted resolution to follow the line of Charu Majumdar unconditionally which others did not agree to. The pro-Charu Majumdar CPI (ML) later split into pro- and anti-Lin Biao factions. The pro-Lin Biao faction became known as Communist Party of India (Marxist–Leninist) (Mahadev Mukherjee) and the anti-Lin Biao-group later became known as Communist Party of India (Marxist–Leninist) Liberation and was led by Jauhar, Vinod Mishra, Swadesh Bhattacharya. As a result of both external repression and a failure to maintain internal unity, the movement degenerated into extreme sectarianism.
