British police arrest 21-year-old man tied to VTech toy hack

British police have arrested a 21-year-old man in connection with the hacking of toymaker VTech Holdings, which exposed the data of 6.4 million children, in what experts said is the largest known theft of personal data targeting kids. "We are still at the early stages of the investigation and there is still much work to be done," Craig Jones, head of the regional cyber crime unit said in a statement. VTech, a Hong Kong-based firm, disclosed the massive data breach early in December.
