Buenos Aires - A survivor of the Argentine military dictatorship who is serving as a witness in trials against perpetrators of human rights abuses during that era has been released by kidnappers nearly 30 hours after being taken captive in an apparent attempt to silence him.
Argentine human rights activist Juan Evaristo Puthod, a survivor of the last dictatorship in the South American country from 1976-83, went missing on Tuesday prompting an intense search effort.
Puthod appeared bruised and exhausted at a hospital after unknown kidnappers took him hostage in the city of Zarate, 80 kilometres north of Buenos Aires.
