Three people believed to have been abducted in Vadamaradchi are being detained by anti-drugs police in Trincomalee.
Mr Jeffrin, George Rasanayagam and V. Michael were believed to have been abducted as they were seized in vans by unidentified individuals and their families uninformed.
The three men were reported missing by their families to Palai and Kilinochchi police and the case reported to the Human Rights Commission.
The inquiries by the Commission led to the discovery that the three men had been arrested by a special drugs force from Trincomalee, despite no record of their arrests being given to local police.
Action is reportedly being taken by Trinco police to bring the men before a court on drug-related charges.
