Sri Lankan Navy arrested a suspected Tamil Tiger rebel trawler off the northern coast Wednesday, defense officials said.
The arrest made in the early hours of the day was following a search by the Navy's coastal surveillance, officials said.
The trawler with four people on board was arrested off the coast of Point Pedro and was taken under Naval escort to Kankesanturai and handed over to the police.
"We found a mobile phone charger and a high frequency radio hidden among the fishing nets on board the trawler," a defense officials in the capital Colombo said.
The arrest coincided with planned action by the Liberation Tigers of Tamil Eelam (LTTE) rebels to reopen their political offices in government controlled areas in the north and east.
The rebels are permitted to do political work in government controlled areas in terms of the February 2002 ceasefire accord.
However, they shut down their political offices during the upsurge of violence from December last year to January.
The military sources said that the planned action to reopen political offices did not materialize Wednesday as the Army declined to comply with the LTTE request to keep the troops 500 meters away from the political offices and also the Army insisted that the rebels would not be allowed to fly their flag at the offices located in areas under government control.
The rebels said they had kept the international truce monitors, the Sri Lanka Monitoring Mission, informed of their plans to reopen offices.
