A Bharatiya Janata Party (BJP) worker was hacked to death late night on Sunday in the Mukkattukara area.
20-year old worker Nirmal was stabbed to death during celebrations at a festival in a temple here.
The BJP state unit has alleged the Communist Party of India (Marxist) (CPM) was behind the incident and has called for a strike in the district today.
The conflict between the BJP-RSS alliance and the CPI(M) has been on a rise for the past few months. Earlier last month, the BJP accused the (CPI(M)) for the murder of one of its workers. A 52-year old BJP worker, Mullapram Ezhuthan Santhosh was killed when he was alone in his house.
Further details are awaited.
