The Fiji Taxi Union is calling for all police officers on duty to be armed with guns.
The Daily Post reports that the call follows the discovery of a 40-year old taxi driver's body in a creek just outside Labasa on Sunday.
Police are treating the case as murder and have arrested three people, who had hired the taxi earlier, for questioning.
The general secretary of the Fiji Taxi Union, Rishi Ram, says criminals behave when soldiers patrol the streets and the community with guns, so police should be equipped with guns to ensure the safety of people.
Mr Ram says they are backing northern division taxi operators who plan to stop services from 6.00pm.
He has called on those responsible for the Labasa murder to be brought to justice and made to pay for their crime.
Assaults and robberies of taxi drivers by those who hire them are common in Fiji while there murders are more occasional.
