New submitter apenzott writes "According to the BBC, a Dutch citizen has been arrested by Spanish police who suspect he was behind the recent Spamhaus DDOS attack, one of the biggest such attacks ever. 'The man arrested is believed to be Sven Kamphuis, the owner and manager of Dutch hosting firm Cyberbunker that has been implicated in the attack.' According to a press release from the Dutch Public Prosecutor (Google translation of Dutch original), the 35-year-old man's computers and other devices have been seized as evidence. The man will be transferred from Spain to the Netherlands shortly. 'Spamhaus is delighted at the news that an individual has been arrested and is grateful to the Dutch police for the resources they have made available and the way they have worked with us,' said a Spamhaus spokesman."
