British police announced today that they arrested a 19-year-old hacker who is  believed to be the leader of the infamous Lulzsec, a hacking group who previously claimed responsibility for cyber-attacks on the US Central Intelligence Agency, multiple Sony Corp websites and the website of Mr Murdoch's British newspaper group, News International.

The teen was found in Scotland's isolated Shetland Islands and used the nickname "Topiary" online. From the Metropolitan Police press release:
The man arrested is believed to be linked to an ongoing international investigation in to the criminal activity of the so-called "hacktivist" groups Anonymous and LulzSec, and uses the online nickname "Topiary" which is presented as the spokesperson for the groups.

He was arrested at a residential address in the Shetland Islands and is currently being transported to a police station in central London. A search is ongoing at the address.
During its run, the group attracted widespread global media coverage for its stunts and has nearly 350,000 followers on Twitter, the messaging website. Topiary's once-voluble Twitter account was completely wiped on July 21st, leaving behind just one tweet. "You cannot arrest an idea."
