Peter O'Neill has not acceded to the demands of students at the University of PNG, who are calling on him to resign over a major fraud case he is implicated in.
Police fraud squad officers had secured an arrest warrant for Mr O'Neill over the matter two years ago, but his lawyers have launched a series of challenges which are yet to be finalised in court.
A spokesperson for the university's student representative council, Gerald Tulu Manu-Peni, said the students were pondering their next move, which could include a mass withdrawal from courses.
