The arrests include one man in the city of Gijón who allegedly had a computer in his house that was used to attack PSN. The same computer was reportedly involved in attacks on Spanish banks and other entities. The other two arrests took place in Valencia and Barcelona, but no further information was provided.
Spain's National Police, according to NYT, claim that the three suspects were part of the "local leadership" of the hacking group Anonymous, and that the police found its suspects by analyzing chat logs and web pages. The arrests were made as part of an investigation that began in October of last year following a hack on the Spanish Ministry of Culture website. Anonymous has previously denied official involvement with the PSN hack, though some members have speculated that the attackers were likely connected to the group.
