Scotland Yard arrested a 19-year old man believed to be LulzSec spokesman and hacker "Topiary"  on Wednesday.  

The man was arrested in the Shetland Islands for his role within the LulzSec and Anonymous hacking groups, which have targeted major companies over the past few years.

"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," the police said.

The man posted on Twitter under the handle "atopiary" and described himself in his bio as, "Simple prankster turned swank garden hedge. Worked with Anonymous, LulzSec, and other such paragons of intense cyber victory. You are free."

His most recent tweet on July 21st perhaps foreshadowed his fate when he wrote, "You cannot arrest an idea."

Topiary was considered to be the hacking group's second-in command and was the main spokesman to the media. This is now the 22nd arrest over the last two weeks in what has been a concerted effort to take down those associated with LulzSec and Anonymous.

Last week authorities arrested 16 hackers in the United States, four in The Netherlands, and now two from England. The investigative efforts are directed at catching the operatives behind PayPal denial of service attacks.

The attacks, levied primarily by Anonymous, were against the company after it suspended the account of WikiLeaks.

PayPal was just one major organization that LulzSec and/or Anonymous have attacked though. LulzSec has also attacked Sony, Nintendo, the CIA, and the U.S. Senate, among other important entities.
