Tongatapu Police are treating the discovery of two bodies last week as suspicious.
The bodies of a man and a woman were believed to be of an Asian couple.
Police Minister Māteni Tapueluelu said the bodies were found with obvious injuries and the couple’s vehicle was missing.
It is not yet known how they died. Police investigation is underway, Hon. Tapueluelu said.
The death comes after two teachers died in a two-vehicle crash on Taufa’āhau main road on Saturday night.
