The girls also claimed that around a 100 girls were not receiving education just because the principal had removed all the male teachers from the college who were teaching there for last many years.
Azizullah, the brother of Saqiba said despite the girls submitting apologies to the college principal for the protest they were not allowed to sit in their final exams and his sister was extremely depressed.
The Balochistan Board of Intermediate and Secondary Education exams are scheduled to start from April 1.
