At least 60 students of a higher secondary school in Murshidabad district of West Bengal fell sick on Saturday and were admitted to different hospitals.
The reason for the sickness of the students of Kavi Nazrul Higher Secondary School at Tikorberia village under Jalangai police station could not be immediately ascertained.
However, Jalangi Panchayat Samiti president Saiful Islam said it could be either due to Hepatitis B vaccination the students were administered on Friday or due to consumption of contaminated puffed rice on Saturday.
As tension mounted in the area after hundreds of people besieged the school, policemen in strength began patrolling the area surrounding the school.
Islam said that while 14 sick students were admitted to the Murshidabad Medical College Hospital, the others were admitted to Domkal Sub-divisional Hospital and a local health care facility.
