Some people alleged that forms in the Akandaberia High School at Kaliachak were given to those students who did not even have the qualifying marks and a clash broke out between two groups, police said.
Malda SP Prasun Bandopadhyay said a police team went to the spot and tried to disperse the two warring groups.
But the groups threw stones and brickbats at the police team. The police then baton charged to disperse the people, the SP said.
