For the first time, the case naming a specific murder of a man in 1980s was registered against Idukki district CPI-M Secretary M M Mani and four others in Rajakad police station in the district, police said.
The case listing conspiracy and murder charges relates to the killing of one Anjeri Baby in 1980s.
Mani, whose speech has landed the party in a serious embarrassment, had already been booked for murder last week for his remarks at a public meeting in Thodupuzha that the party had eliminated political foes in the past.
A special investigation team set up by Congress-led UDF government in the state has already summoned Mani to appear before it for questioning in connection with his speech.
In the first case in which Mani had been charged with murder, abetment and concealing information, police had not named any specific victim.
Mani, who had remained definat refusing to step down from the organisational post, also seems to be facing disciplinary action by the party which had described his statement as a deviation from the party ideological line.
According to party sources, Mani is expected to face disciplinary action as the party's central and state leaderships viewed his controversial speech seriously.
The sources said CPI(M) state Secretary Pinarayi Vijayan made this clear at a meeting of party functionaries from southern districts here yesterday.
In Kochi, Vijayan tonight termed as illegal the filing of the case against Mani for his controversial speech, saying no crime can be registered on the basis of that speech.
Senior leader and Politburo member S Ramachandran Pillai said Mani's statement was a "mistake". The party does not annihilate its adversaries by conspiring and drawing up a list, he said. "The Marxist party is against any violence."
Mani's speech came at a time when CPI-M has been in the dock after the arrest of some of its activists in connection with the recent murder of party rebel and Revolutionary Marxist Party leader T P Chandrasekharan.
