"An attempt was made by two provincial councillors in Chavakachcheri yesterday to commemorate LTTE members," police spokesman and Superintendent Ajith Rohana said.
The attempt - that defied a public ban on such public commemorations - was blocked by the police, he said.
Tamil sources said M K Shivajilingam and Ananthi Saseetharan, both members of the northern provincial council, had gone to provincial council offices in Chavakachcheri to conduct a memorial for those killed during the last phase of the war.
The government last week banned all public commemoration in the battle-scarred north.
