At least 27 Tamils were arrested overnight in the run-up to Maaveerar Naal, in the Chunnakam police district, in Jaffna.
Local sources told the Tamil Guardian that they were arrested on suspicion of being involved in Maaveerar Naal events.
However Chunnakam police said they were detained for "acting suspiciously" at night.
