Preman of Koothuparambu municipality, who sustained stab injuries in the attack last night while returning home after attending a marriage function died at the Thalassery cooperative hospital this morning, police said.
The CPI(M) has called for a hartal in Kannur district this afternoon to protest the attack.
Police said they were investigating whether the latest attack was a sequel to previous clashes involving CPI(M) and BJP workers for the last three weeks in the district.
A BJP panchayat president and two CPI(M) workers were seriously injured in separate incidents of attacks allegedly by rival party workers in Kannur yesterday.
The District Collector has convened an all-party meeting tomorrow in connection with the incidents.
