The Northern Provincial Council (NPC) member, T Ravikaran and six others, who were arrested after participating in a protest earlier this month against illegal fishing in Mullaitivu by Sinhala fishermen, have been ordered to appear before the Magistrate's court on October 30.
Mr Ravikaran and others were charged with allegedly causing damage to public property during the protest.
Local fishermen protested for almost a week against police and government inaction against illegal fishing by Sinhala fishermen in the area.
Three Sinhala fishermen were arrested last week over the torching of Tamil fishermen's boats and huts, in what local fishermen believe were reprisal attacks for the protests. Hundreds of thousands of rupees worth of fishing equipment was destroyed.
Some of the Sinhala settlers left the area under police protection following the incident as tensions continued in the region.
