Kilakila secondary has a population of over 1,000 students.
It is one of the oldest schools in the city which saw some classrooms rehabilitated in the past two years at a cost of K1 million, by the office of the Moresby South MP and NCD Governor.
One of those classrooms, a double-storey building, was razed last Friday afternoon, allegedly by a student who was not happy about being disciplined.
Badili Police Station Commander, Bill Werake, said the student (name withheld) was picked up on Tuesday afternoon while he was in class.
