FBI agents in the US have searched the house of a teenager in Hamilton, Ohio, whom they suspect of being a member of the hacking group LulzSec.

A report in the local newspaper quoted an FBI agent, who said that federal agents had searched a house on Monday 27 June at which the suspect had lived.

Nobody was charged after the search. The FBI is believed to have been acting on information from interviews and data gleaned from Ryan Cleary, who lives in Essex and has been charged with five offences under the Computer Misuse Act. LulzSec denied that Cleary had any involvement with the group in a tweet after his arrest, and suggested he had only hosted a chatroom for them.

The website Threatpost reports that the Ohio teenager was known within LulzSec as "m_nerva", who leaked text logs of discussions between the group after they had hacked into the website of an FBI affiliate at the beginning of June.

In those discussions, the apparent leader, called "Sabu", warned them not to discuss what they were doing with anyone.

After the logs were leaked, the person controlling the LulzSec Twitter account threatened m_nerva saying "Remember this tweet, m_nerva, for I know you'll read it: your cold jail cell will be haunted with our endless laughter. Game over, child."

LulzSec also released alleged details of the identity of m_nerva and another member; one of the names was of a person who lived in Hamilton, Ohio. The other allegedly lived in Halethorpe, Maryland.

Last week FBI agents searched the house of a woman in Iowa and questioned her about links with the group. LulzSec said in a statement that it had six members, though it never stated their gender. But The Guardian understands that one key player was a female known in the group as "kayla" who carried out a number of website attacks.

LulzSec announced that it was disbanding in a message on Sunday , and its senior members appear now to have tried to meld back into the larger Anonymous hacker collective, from which they are attempting to drive its present direction.
