Ten people were injured as police went into action to free invigilators from the SSC examinees' confinement at Panchagarh Girls' High School centre yesterday.
The trouble began as the members of a vigilance team including a magistrate took objective answer papers of chemistry 10 minutes before end of the examination time when the examinees involved in copying from one another at Room No 202 in the centre, sources said.
The agitated examinees encircled the members of the vigilance team and kept them confined for an hour. As they declined to free the members, police charged batons on the students.
Nine SSC examinees and a pedestrian were injured during the incident.
Later the students joined by their guardians barricaded Panchagarh-Dhaka highway demanding punishment of the invigilators. They also set fire to a motorbike in front of the school.
On information, Additional Deputy Commissioner Ahsanul Parvez went there and persuaded the demonstrators to leave the place by assuring them of taking action against the 'responsible' invigilators.
When contacted, Headmistress of Panchagarh Girls' High School Rekha Rani Debi, also the centre secretary, denied taking objective answer papers before end of the time.
