An 18-year-old British man has been arrested in relation to the PlayStation Network and Xbox Live DDOS attacks at Christmas.

The man is accused of unauthorised access to computer material following the attacks that disrupted Microsoft's and Sony's online services over the holiday period. He is also accused of knowingly providing false information to law enforcement agencies in the US.

The arrest came as part of a joint operation between the South East Regional Organised Crime Unit (Serocu), the North West Regional Crime Unit (Rocu), the National Cyber Crime Unit (NCCU), and the Federal Bureau of Investigation (FBI).

"We are still at the early stages of the investigation and there is still much work to be done," Craig Jones, head of Serocu's Cyber Crime Unit, told the BBC. "We will continue to work closely with the FBI to identify those who commit offences and hold them to account."

The Xbox Live service is currently experiencing (unrelated) issues, with Xbox 360 gamers struggling with online purchases, some app functionality and accessing cloud storage.
