A 19-year-old British man was arrested on Tuesday in connection with the Sony hacking, according to the London Metropolitan Police.

Ryan Cleary, who lives in Wickford, Essex, northeast of London, was arrested by officers from the Metropolitan Police Central e-Crime Unit working in co-operation with the FBI. He is under suspicion of violating the Computer Misuse Act and fraud, and was taken to a central London police station, where he remains in custody.

The arrest follows a probe into network intrusions and distributed denial of service attacks against a number of international business and intelligence agencies, including Sony, the U.S. Senate and the CIA.

While the police have yet to confirm the connection, a London Metropolitan spokesperson told Variety that it was “fairly confident that the Sony hack is connected to the arrest.”

The raid was said to be a pre-planned, intelligence-led operation and searches at the residential address have led to “the examination of a significant amount of material.”

In April, Sony’s PlayStation Network and streaming service Qriocity went down after a large data breach, when hackers took information from more than 100 million accounts, costing Sony an estimated $171 million. In early June, hackers known as LulzSec claimed to have breached the Sony Pictures website. Sony confirmed the breach, which revealed passwords and personal info.

It contacted the U.S. Federal Bureau of Investigation to assist with the cybercrime.

LulzSec has been taking credit for a number of high-profile hacks in the media and entertainment world, including pubcaster PBS, and claiming security breaches on the CIA website.

The group has posted information on its website that it claims is proprietary from Sony Pictures and other Sony websites.

“Seems the glorious leader of LulzSec got arrested,” LulzSec said via its Twitter account on Tuesday. “It’s all over now…wait…we’re all still here! Which poor bastard did they take down?”
