Interpol has cracked down on the Anonymous hackers group, arresting 25 suspected members of the hacker collective across Europe and South America.
Arrests were made in Spain, Argentina, Chile and Colombia by national police working under Interpol's Latin American Working Group of Experts on Information Technology Crime.
Those arrested include hackers "Thunder" and "Pacotron", two 17-year-old Chileans and others aged between 17 and 40 years of age.
Anonymous, whose high profile hacks include the interception of a phone call between Scotland Yard and the FBI, can be traced back to the US sharing site, 4Chan.
Anonymous has become increasingly active in reaction to web censorship efforts like SOPA and PIPA in the US, and ACTA in the UK and EU, and broadly supports Wikileaks.
According to AP, an official Spanish police statement says that two servers in Bulgaria and the Czech Republic which are used by the hackers have been shut down.
In an official statement, Interpol said that 250 pieces of IT equipment, mobile phones, payment cards and cash were seized in raids on 40 premises across 15 cities.
The arrests follow four others made earlier in the week. Interpol says their operation targeting Anonymous is ongoing.
