Sri Lankan police have made a series of arrests, which they according to them are linked to combating terrorism, three years after the separatist Tamil Tigers were defeated.
According to a top official, up to 25 people are being held.
Officials gave differing accounts of the number of arrests made by anti-terrorist police in the latest raids, the BBC reports.
The report quoted police spokesman Prishantha Jayakody, as saying that 10 men had been detained in the Jaffna area, all of them accused of "terrorist activities" with the Tamil Tigers or LTTE before 2009.
Jayakody said that none those being held had completed a government rehabilitation course for LTTE suspects and none had surrendered to the police or army at the end of the war.
"They were arrested at different places on the Jaffna peninsula and are now in Vavuniya. All the families have been informed," he added.
According to the report, espousing separatism is illegal in Sri Lanka.
Suspects can be held without charge for 18 months. (ANI)
