Today, UK police arrested an 18-year-old man in connection to the hack on PlayStation Network & Xbox Live on December 25th, 2014.
British authorities, in conjunction with the FBI, seized electronic and digital devices that will be examined by

Craig Jones, Head of the Cyber Crime Unit at SEROCU, stated the following: “This investigation is a good example of joint law enforcement cooperation in relation to a type of criminality that is not restricted by any geographical boundaries.
