The National Crime Agency has warned hackers they will be tracked down and brought to justice, after 28-year-old Lauri Love was charged with hacking into US government computer systems.
The NCA said: "Cyber-criminals should be aware that no matter where in the world you commit cyber crime, even from remote places, you can and will be identified and held accountable for your actions.
"The NCA has well-developed law enforcement alliances globally and we will pursue and deal robustly with cyber-criminals."
