PPC Manus, Chief Inspector David Yapu, said a 16-year-old Grade 7 student who was allegedly abused between 2017 and 2018 revealed the incident to her teachers and village court officials who referred the matter to police for investigation.
The victim had been interviewed by police and was referred for medical examination.
The father is yet to be arrested but PPC Yapu said reported sexual offences in Manus Province have increased and it is through police awareness that cases are being reported.
