Spanish police arrested four suspected hackers of the subversive online movement Anonymous accused of sabotaging websites and publishing confidential data on the Internet, officials said Wednesday.

They are suspected of hacking political parties' and companies' websites and adding fangs to the faces of leaders in photographs online, and publishing data identifying top officials' security guards, police said in a statement.

The arrests were part of an international raid against Anonymous in which police traced suspects by trawling through computer logs, it said. It also netted 10 suspects in Argentina, six in Chile and five in Colombia.

Police said one of the suspects went by the nicknames Thunder and Pacotron and was suspected of running the computer network used by Anonymous in Spain and Latin America, via servers in the Czech Republic and Bulgaria.

He was arrested in the southern Spanish city of Malaga.

Two of the suspects were in detention while one was bailed and the fourth was a minor who was left in the care of his parents.
