A Papua New Guinea police commander says a long period of dry weather could force a withdrawal of services in the Western Province district of North Fly.
North Fly Superintendent Joseph Puri said to if worst came to worst, they will release all the suspects detained at the Kiunga police station.
Mr Puri said the drought had caused the Fly River level to drop and ships are not bringing goods to the area.
He said food was running dangerously low in the shops in Kiunga and Tabubil.
Mr Puri told the National newspaper the towns depend on the Fly River for the transportation of supplies from Port Moresby.
The police commander said there was no water in the tanks and the situation was very alarming.
