The victim was found dead on August 7, 2017.
A concerned Governor Juffa said we need laws to protect our children to prevent such abhorrent behaviour.
He said significant education and awareness to help children report and avoid becoming victims and serious penalties must also be done.
“I will review the laws and see what can be done to improve them for greater protection of our children,” Juffa told Loop PNG.
According to New Ireland Provincial Police Commander John Midi, the three suspects are now in police custody awaiting court hearing.
He told Loop PNG that the names and identity of the suspects are yet to be released by the investigation team.
The victim would have turned seven this November.
The body of the victim was laid to rest on Monday, August 21.
