At least seven persons were injured in a clash between two groups over possession of a tea plantation in North Dinajpur on Sunday.

Sources said two families, residing in neighbouring villages, had a dispute over the possession of a tea plantation spread over an area of seven cottah located in Balabari village under Daspara panchayat of Chopra block.

On Sunday, Haripada Mondal, representing one of the families, went to the plantation and tried to put boundary pillars on the plot. Jatin Roy, who represents the other family, objected and soon both the families and their associates attacked each other with daggers, iron rods and sticks.

The sources said five persons from Roy’s family and two from Mondal’s family had sustained injuries. They had been admitted to the NBMCH.

A police team is deployed in the area to monitor the situation.
