A student was injured due to blast at a North Nazimabad school on Friday. Investigations into the incident established that the student injured was himself behind the blast that had caused enough panic last week.
Police questioned five students including two real brothers, which led to the revelation. All of the students were later allowed to go home.
The class 10 student was not allowed to sit in exam over non-payment of fee, at which he ignited a firecracker that somehow exploded in his hand.
As the Rangers reached the school, the injured student clamoured and misguided that some explosive device was thrown from outside the school.
