The International Secretariat of the World Organisation Against Torture has voiced concern over the condition of a West Papuan prisoner at Indonesia's Abepura prison
The Geneva-based Secretariat says it's been informed about the deteriorating health of Matan Klembiap by the British-based Indonesian human rights group, Tapol.
Mr Klembiap was taken into police custody in the Papua provincial capital Jayapura in February and allegedly tortured by police, beaten with rattan sticks on the back and electrocuted in the face.
Facing weapons-related charges, the 41-year old has not received medical care since he was detained.
Furthermore, he reportedly does not have legal representation and he has been denied family access.
The Secretariat has urged Indonesian authorities to carry out a thorough and independent investigation into the allegations, in accordance with the United Nations Convention against Torture to which Indonesia is a State party.
