The union government was considering whether or not to order the CBI probe, Union Minister of State in the PMO Jitendra Singh said in a letter to Kerala Home Minister Ramesh Chennithala.
Chennithala said the state government had thrice written to the Centre seeking CBI probe into the conspiracy behind the attack on Chandrasekharan.
The Centre's reply was to the third letter sent by the state, Chennithala said in a statement.
Chandrasekharan, a former CPI(M) rebel from Onchiyam, was hacked to death by a gang allegedly at the behest of CPI(M).
Eleven persons, three of them local CPI(M) functionaries, had been sentenced to life imprisonment in the case by a local court which had stated that the motive of the crime was political and not personal enmity.
