BJP and CPI(M) supporters clashed at Dharmanagar in North Tripura district on Sunday, with both the parties blaming each other for the incident.
While the BJP claimed that four party supporters were injured in the clash, the police were yet to confirm it.
The saffron party blamed the CPI(M) for the clash, while the Left party termed the allegations as "baseless".
Fifteen motorbikes and a car were gutted during the clash, the police said.
Additional SP H Francis Darlong said that the situation has been brought under control and a large contingent of Tripura State Rifles paramilitary personnel has been deployed in the area.
Deputy Speaker of Tripura Assembly Biswabandhu Sen alleged that the BJP workers were attacked by the CPI(M) workers at West Chandrapur during campaigning for the rural polls.
