Reuters is reporting three unnamed suspects were arrested in three separate Spanish cities. There are few details at this time, but all three suspects were described as being in their 30s. According to the report, Spanish police claim that the suspects "were guilty of coordinated computer hacking attacks from a server set up in a house in Gijon in the north of Spain."
If the people arrested were indeed involved in the attack on the Playstation Network, I will have to say that I am impressed with investigators. In all honesty I doubted that anyone would ever be caught and punished for this crime, and that years from now, some old man on his death bed would claim responsibility. Here's hoping justice is served if they are indeed guilty.
