Madrid - Police have arrested a former employee of the Spanish secret service CNI for spying for another country, CNI director Alberto Saiz said Tuesday in Madrid. The suspected double agent is believed to have earned a lot of money from selling sensitive information to a foreign spy service between 2001 and 2004, Saiz said.
The suspect's actions revealed the identities of several Spanish agents.
Spanish radio reported that Russia was the recipient of the information, but there was no official confirmation of this.
The security of Spain, NATO and the European Union were not affected, Saiz said.
The former agent was arrested Monday on the Canary Island of Tenerife.
