The hacker has already said that the emails will not be revealed yet. Sabu also claimed that hackers have already breached security systems of banks including HSBC and "a few others" but are yet to gain access to some sensational information.

"There are a lot of interesting dumps we're sitting on due to timing," the hacker wrote on his Twitter account.

He had said that after a series of arrests in the UK and US of a number of people believed to be linked with the hacking group, he is on the run from the authorities. He wrote through messages that he is on the run and is at the risk of being detected through this friends and not `these idiots who hide behind the patriot veil'. He also says that "technically, I'm on the run, so there you go."

LulzSec is believed to be an offshoot of the Anonymous hacking group, who claims be an online free speech hackavist.
