This is not the Topiary you are looking for

When the Metropolitan Police arrested a 19-year-old Shetland Islands resident a couple of days ago, they crowed that they had collared the LulzSec and AnonOps kingpin known to his fellow hacktivists as 'Topiary'.

The cops now say the man is 18 years old not 19 and there's increasing speculation that they've got the wrong Topiary.

In a feat of misdirection worthy of Derren Brown, it seems like the real Topiary might have left the Met with even more egg on its face, as tales of doxing double-bluffs and Swedish hackers polishing up their best Highland accents start flooding the web.

It turns out that there are at least two - and possibly many more - people going by the handle Topiary and whether the cops have collared the right one remains to be seen.

All we know is that the Twitter account of the person most people consider to be the 'real' Topiary has been cleaned out leaving a single posting which reads, "You cannot arrest an idea," a line which has become an Anonymous battle cry in the wake of a spate of high-profile arrests across the globe.
