After the arrest of a 19-year-old in connection with the Sony hack, LulzSec came up with yet another tweet ridiculing desperate police efforts to close in on the group. Immediately after the arrest, there had been media reports claiming that the arrested teenager was actually the leader of the hacking group.

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?  tweeted LulzSec several hours after London's Metropolitan Police took the youth into custody from Essex, outside London.

However, there has been no official statement from the authorities yet, confirming the role of the alleged hacker in breaking into the Sony network and websites of intelligence agencies like Serious Organized Crime Agency (SOCA) and CIA.

Sources confirm that police had come across a ''significant amount of material'' from the suspect. The same will be probed in detail to see if he is in possession of sensitive information related to the prominent hacks.

Although LulzSec is looking to downplay the incident, it cannot be ruled out that the arrested hacker has nothing to do with the group. The recent tweet could possibly be an attempt to distract investigation.

LulzSec had recently crossed 1,000 tweets ever since it went on the rampage. As a sort of celebration of the landmark achievement, the group had posted sort of a manifesto urging all those mooting for Internet freedom to be thankful about their efforts.

Most of the group's exploits have been in the media glare partly because of the impact they have made, and also because of LulzSec's own claims that they were 'entertaining'.

While Sony reported the cost of the attack as a whopping $171 million, LulzSec suggests it is sheer fun to have access to the account information pertaining to a few hundred thousand gaming enthusiasts, and more so when such information is made public.

Despite the tall claims made by the group, authorities are not fully convinced about LulzSec having made the PlayStation breach.

Earlier, LulzSec had created a storm by hacking into the website of PBS, the American public broadcaster. After gaining access, the group had posted a rather entertaining story about late rapper Tupac Shakur, claiming that he is alive in New Zealand.

Intelligence agencies are hoping that the arrest of the teen hacker will eventually lead them to more of the group's members in the weeks ahead.
