Police say the group never met, but co-ordinated their attacks
Spanish police have arrested five hackers they describe as being among the most active on the internet.
The hackers, who include two 16-year-olds, are accused of disrupting government websites in the United States, Asia and Latin America.
Police say they co-ordinated attacks over the internet and hacked into 21,000 web pages over two years.
The inquiry began in March after a Spanish political party's site was disabled after the Spanish election.
The five were arrested in Barcelona, Burgos, Malaga and Valencia.
