According to a press release by the Openbaar Ministerie (the Public Prosecution Office), a dutch man with the initials SK has been arrested in Spain (English translation) for the dDOS attacks on Spamhaus. Authorities in Spain have searched the house where SK was staying and seized electronic devices including computers and mobile phones.
Brian Krebs has more, including multiple sources that identify SK as Sven Olaf Kamphuis. Sven Olaf Kamphuis was quoted in many articles about the dDOS, including the NY Times and various reports by Ken Magill.

Spamhaus dDOS

I got mail late last night from one of the Spamhaus peeps telling me that they were under a distributed Denial of Service (dDOS) attack. This is affecting email. Incoming email is delayed and they’re having difficulty sending outgoing email. This is affecting their responses to delisting queries.
