Spanish police announced Friday that three arrested were made of members belonging to the hack activist group Anonymous who allegedly were responsible for the attacks made on Sony and on banks and other government websites.

Spain police also said they have been one of the first police forces in their country devoted to tracking Anonymous, who may have been responsible for several distributed denial-of-service attacks (DDOS) against business and government organizations.

Arrest were made in Barcelona, Alicante, and Valencia. One arrest in the city of Gijón had a computer in the house which was used to attack the PlayStation Network. The arrest not only helped officials pinpoint attacks on Sony PlayStation Network, but also dozens of other attacks including the bank BBVA, an Italian utility company called ENEL and government websites in Egypt, Algeria, Libya, Iran, Chilie, Colombia and New Zealand.

Anonymous have targeted groups like Scientology website and companies that have cut its ties with WikiLeaks, like Amazon.com, MasterCard, PayPal, PostFinance and Visa.

Spanish police also said Anonymous is responsible for attacks on Catalan police websites and an attack on the Central Electoral Board and UGT trade union back in May.

Names of those arrested have not been released yet.
