They also demanded that the deputy director, who is now acting director, resign. They gathered in the basement of the school after the deputy director, whose name has not been revealed, ended the sports day early on Saturday despite the fact that it had not yet finished. The students refused to return to their classes and demanded his superiors investigate the issue. The protest, in which students used megaphones while criticising the deputy director, continued for hours while the deputy director remained in his room. He later told reporters that the sports day started on Thursday and was scheduled to end Saturday.
