At least four persons were injured after two groups clashed in Brindaban Municipality of Rautahat district on Saturday following a dispute over tax on aggregates.

The locals set a hut set up to collect the tax on fire, accusing Mayor Vinod Patel of taking a capricious decision on collecting the tax on aggregates extracted from local rivers.

According to Bir Bahadur Budha Magar, Rautahat chief district officer, police personnel have been fanned out to take the situation under control.

Local leaders of the Nepali Congress, the CPN-UML, the CPN (Maoist Centre) and the Janata Samajbadi Party on Friday had requested the mayor not to levy tax on the extraction of aggregates.

Despite assurance from the mayor, taxes were collected on extraction which led to the clash between supporters of the mayor and locals, said UML leader Prem Shankar Yadav.
