As the news of the arrest of 19-year old mastermind behind the hacker group LulzSec spread, they tweeted: Seems the glorious leader of LulzSec got arrested, it's all over now... wait... we're all still here! Which poor bastard did they take down?

Speculation is rife regarding the identity of the arrested hacker(s). While some said arrested person was Ryan who hacked Anonymous IRC networks, yet others speculated that the arrests have been random under the pressure to find the hacker group wrecking virtual havoc across the planet.

LulzSec also denied hacking into UK Census and stealing information. They tweeted: Just saw the pastebin of the UK census hack. That wasn't us - don't believe fake LulzSec releases unless we put out a tweet first.

Anyone in the world can copy and paste The Lulz Boat ASCII art and general lighthearted theme. Smarten up, check the feed first. #AntiSec, wrote LulzSec.

Within a minute they applauded the effort of whoever hacked the UK Census: But hey, if someone out there hacked the UK government in the name of #AntiSec, well done sirs!
