A sudden police operation round-up in Thunnalai on Friday morning has resulted in three arrests.
Point Pedro police said they carried out the operation in the early hours following an anonymous tip-off.
Thunnalai and surrounding villages in the Vadamaradchi area have been subjected to repeated operations, including deployments of Special Task Force troops.
Relations between locals and security forces remain tense since police shot and killed a Thunnalai man in July.
