The incident occurred on Monday when a male student was alleged to have committed blasphemy during an exchange of words with a Muslim friend, a situation which caused tension in the school.
It was also learnt that a mob had penetrated into the house where the alleged person was said to be hiding to avoid being lynched. After they gained entrance, they set the house ablaze along with seven other persons in it.
Police in Zamfara state confirmed the incident and imposed an indefinite curfew in the town with a view to restoring peace in the area.
Spokesman of the police in the state, Deputy Superintendent of Police (DSP) Shehu Muhammad, in a press statement, cautioned any person or group of persons found violating the curfew order to desist from doing so or they would be arrested and prosecuted.
However, the authority of the polytechnic has closed down the institution with immediate effect for sanity.
