Front Line is deeply concerned following reports of the continued detention of Natalio Ortega Cruz, Romualdo Santiago Enedina, Raúl Hernández Abundio, Orlando Manzanarez Lorenzo and Manuel Cruz Victoriano, all of whom are members of the Organización del Pueblo Indígena Me'phaa (Organisation of the Me'phaa Indigenous People, OPIM). They were arrested on 18 April 2008 and detained in Ayutla, in the State of Guerrero, and are among a group of fifteen OPIM members whose arrests had been ordered on 11 April 2008. The remaining ten members of the OPIM are reportedly at risk of arrest at any time. Since 2002, the OPIM has worked in the defence of indigenous rights in the communities of Ayutla de los Libres and Acatepec, Costa Montaña de Guerrero.
