RSS-BJP leaders alleged that the CPI(M) was behind the killing and gave a call for a dawn-to-dusk hartal in the state on Tuesday.
Four persons, stated to be CPI(M) workers, have been taken into custody for questioning in connection with the incident, police said.
BJP President Amit Shah, who was in the state on Monday, condemned the killing at a convention of party workers. The party has pledged support to the hartal.
The area, which was witness to violence involving RSS and CPI(M) workers in the past, had remained largely calm in the last few years.
But tension resurfaced with BJP and CPI(M) poaching workers from each side in recent times.
