US Federal Bureau of Investigation agents carried out a raid on the home of an Ohio man suspected of being a member of the Lulz Security hacker group, The Wall Street Journal reported Thursday.

An FBI spokesman confirmed to AFP that FBI agents had searched a home in Hamilton, Ohio, on Monday on the basis of a sealed federal search warrant but declined to provide any details about the raid.

"Because it's sealed we can't comment on the purpose or what, if anything, was taken," the spokesman said. "All I can say is that nobody's been arrested."

The Journal said the man whose home was raided appears to have links to Lulz Security, the hackers who have claimed responsibility for a string of recent high-profile cyberattacks.

Lulz Security has claimed responsibility for hacking the websites of the Central Intelligence Agency, the US Senate, Sony, the Arizona Department of Public Safety and others.

On Saturday, Lulz Security said in a message uploaded to The Pirate Bay file sharing website that it was ending its Internet rampage.

The Lulz farewell contended that the group had a crew of six people and implied the plan from the outset was for the hacking campaign to last 50 days.

A British teenager suspected of involvement with Lulz Security was arrested earlier this month.

Ryan Cleary, 19, has been charged with targeting the website of Britain's Serious Organized Crime Agency -- the British equivalent of the FBI -- with a distributed denial of service attack.

DDoS attacks overwhelm websites with requests, causing them slow down or be inaccessible.

Lulz Security staged a number of DDoS attacks on websites, including that of the CIA, and also carried out a number of large-scale data thefts.
