Amnesty International (AI) has launched an online petition calling for the release of Muslim politician Azath Salley.
The online petition urges SL President Mahinda Rajapaksa to free Salley or charge him and while in custody to ensure he is treated humanely and allowed access to his family, his lawyers and any medical care he may require.
Salley was reportedly detained under the Prevention of Terrorism Act but without any charges being specified against him, Amnesty International said.
State media has reported that he was arrested over alleged links to terrorism and attempts to create communal disharmony in Sri Lanka.
â€œUnder international human rights law, all people have the right to be informed immediately of the reasons for their arrest and of any charges against them, the right to challenge the lawfulness of their detention, the right to a fair and prompt trial and the right to be free from torture,â€ Amnesty International said in the petition.
