New Caledonia's Union of Kanak and Exploited Workers has called a general strike for tomorrow in protests against what it calls recent incidents involving police and the judiciary.
The union, which is also calling on a march in the streets of the capital Noumea, says in a recent incident, police intervened to put a stop to a party held in a public place.
The union plans a gathering outside the French high commission for a march to the court.
A newspaper says one of the union leaders was involved in the incident and is now facing charges for assault on a police officer.
The Union President, Gerard Jodar has accused French police and the judiciary of seizing every opportunity to destabilise the pro-independence union.
