An alleged commander of the 48th Front of Colombian guerrilla group the FARC was captured in Quito by Ecuadorian security forces.
Fabio Ramirez Artunduaga, alias "Danilo," was arrested by Ecuador's police and army using information from the Colombian military, according to reports.
The suspected rebel was set to be handed over to Colombian authorities on Monday.
Colombian General Juan Carlos Salazar said that Ramirez had gone to the neighboring country for medical treatment, and that his capture would make southern Colombia more peaceful.
The alleged Revolutionary Armed Forces of Colombia (Fuerzas Armadas Revolucionarias de Colombia - FARC) member was detained, alongside his female companion Yanenci Hoyos Alarcon, after they were unable to produce valid identification.
