A British youth has been arrested over the hack that brought down the Playstation network and Xbox Live over the holiday period.
UK police are working in tandem with the FBI to track down the perpetrators, who identified themselves as the Lizard Squad.
In addition to arresting the 16 year old youth, the police from the South East Regional Organised Crime Unit (SERCO) seized computer equipment, which they will now scrutinise.
SERCO said it is working with both business and the academic world to create specialist tools to protect the public.
The Sony and Microsoft hacks happened on Christmas Day, using a distributed denial of service (DDOS) attack.
The police said they were still in the early stages of its investigation.
