Police presence at Sserwanga Lwanga Memorial School, in Kalangala district has been stepped up to avert a possible outbreak of violence. Fears are rife that a group of students who were this morning denied entry into an examination hall for lack of identity cards could launch retaliatory attacks. Thirty-eight students were Monday morning blocked from sitting the Geography examination paper after they failed to present valid identity cards. The students argued that this was not a mandatory requirement, contrary to the UNEB requirements, which require candidates turning up for UNEB exams to present a valid identity card. The school headmaster stood his ground and maintained that no candidate would be allowed into the examination hall without a valid ID. Enraged by the school's decision, the students vowed to disrupt the exam session. Some rushed back home and returned with their parents. The parents pleaded but in vain with the headmaster to be allow their children sit their exam. The parents presence did not change the status either. On hitting a dead end, the student took their case to the district police commander. Godfrey Matte, the Kalangala DPC, admits that the students approached him for his intervention. He has described it as unfair for the school to deny the students an opportunity to sit for their paper. The DPC says that it would have been proper to allow the students sit the paper as they sort out the matter before the next paper commences at 2:00pm. Matte has cautioned students to be calm as they negotiate issues with the school authorities.
