The 57 organizations and persons signatory to the letter, which work for the protection of human rights and the environment, express their deep concern at the detention of Mr. Marco Antonio Suástegui, leader of the Consejo de Ejidos y Comunidades Opositores a la Presa La Parota – CECOP (Council of Communal Lands and Communities Opposing the La Parota Dam), on 17 June by members of the Ministerial Police of the Attorney General of Justice of Guerrero State.

We call upon the Mexican State to take effective and urgent measures to guarantee the human rights of Mr. Suástegui and the important work that the human rights defender performs in defence of the Papagayo River. In particular, we consider it fundamental that the State:

• Take measures to ensure that the competent authorities guarantee the right to a defence and due process of Mr. Marco Antonio Suástegui, and reverse any action taken in the detention procedure and past transfers that tainted by illegalities,
• Take measures to guarantee his physical and psychological integrity, and
• Take all necessary measures to secure the work for the defence of human rights and the environment undertaken by Marco Antonio Suástegui, and take an active role in avoiding any act that hinders the actions taken to defend the Papagayo River.
