More than 3,000 people marched in silence through New Caledonia's capital, Noumea, on Friday to express concern at a recent spate of violent attacks in the territory.
Marchers wore stickers saying "stop the violence" and carried placards that read "We are all Daniel", referring to 71-year-old retiree Daniel Monteiro, who was found drowned, bound and beaten in a stream in July.
The president of the Chamber of Commerce and leader of the procession, Jennifer Seagoe, handed a white paper to the French High Commissioner calling on the government to introduce additional measures to counter violence.
As well as Mr Monteiro's muder, the last two weeks have been marked by a series of murders and violent attacks that have sparked a wave of indignation and increased a sense of insecurity.
