A woman was in custody Sunday on suspicion of belonging to the Revolutionary Armed Forces of Colombia, or FARC, the Spanish Interior Ministry said.
The woman, a Spanish national identified as Maria Remedios Garcia Albert, 57, was arrested Saturday morning in San Lorenzo de el Escorial, 36 miles ( 58 kilometers) northwest of Madrid, the ministry said in a statement, the AP reported.
Once police investigations have concluded, Garcia Albert will appear before the National Court No. 5, which is presided by specialist anti-terror judge Baltasar Garzon, on at least one charge of belonging to a terrorist organization, the ministry said in a statement late Saturday.
The arrest took place in collaboration with Colombian police based on information found in computers that belonged to guerrilla commander Raul Reyes who was killed in March, the ministry said.
FARC rebels have been fighting against elected Colombian governments for 44 years.
The suspect is believed to have used a number of aliases to communicate with FARC leaders like Reyes - whose full name was given as Luis Edgar Devia Silva - and Ovidio Salinas Perez, also known as Juan Antonio Rojas, the ministry said.
It said she is believed to have traveled to the FARC's secret camps in Colombia during 2007, where she liaised directly with Reyes, the ministry said.
She is also believed to have provided cover and handled money for FARC members in Europe, principally in Switzerland and Sweden, as well as in Colombia, the ministry said.
Garcia Albert is suspected of having used her job in OSPAAAL, a non-governmental organization linked with Latin America, Asia and Africa - a post she held until a few months ago - as cover for financial activities in support of FARC, the ministry's statement said.
