Update: New information from a self-purported Anon member, quoting an anonymous (lowercase a) source. Via Twitter:

 "The good news everybody: Ryan has little to do with #LulzSec besides running IRC. All 6 members of @LulzSec are fine and safe." #AntiSec 
 
 So! This, if it's true, means that the perp is named Ryan, but wasn't part of LulzSec's integral fuck-shit-up operations. It would also suggest that there are only six members of LulzSec's core team. But again, if it's true. 
 
 Update 2: Another Anon Twitter account has chimed in, downplaying the significance of the arrest:

 If it is Ryan then they're alright. lol #LulzSec 
 
 The "if" in there indicates there may be some internal confusion within the AntiSec campaign as to who has actually been arrested. 
 
 Update 3: LulzSec's official Twitter account has joined the this-doesn't-matter chorus: 
 
 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? 
 
 Update 4: Well this just got a bit more interesting! Yet another Anon Twitter user is claiming the Ryan in question is Ryan Cleary—a kid previously associated with attacking Anonymous in an attempted "coup d'etat" of sorts, Hacker News reported in May: "Mr Cleary was accused of stealing passwords and targeting the network servers used to keep Anonymous's websites running."

 Cleary's personal information was then revenge-posted online—pinning him to Wickford, Essex, exactly as the BBC said earlier this morning. 
 
 So this is strange. Ryan was apparently despised by Anonymous, and described today as a LulzSec IRC admin. With the two forces united for the time being, his place in all of this seems... tense.

 Update 5: LulzSec's put out a further clarifying tweet, this one more conclusive than the last: 
 
 Ryan Cleary is not part of LulzSec; we house one of our many legitimate chatrooms on his IRC server, but that's it. 
 
 So, despite whatever beef Ryan had with Anon, LulzSec's just been using him for his servers, and is distancing itself from him in any other capacity. ||||| NEWS

 According to a statement from the Met on Tuesday, searches took place at a residential address in Wickford, Essex, and the teenager was arrested on Monday night on suspicion of offences under the Computer Misuse Act and Fraud Act. The investigation involved the FBI and, according to some reports, the attacks may correlate to those perpetrated by the LulzSec and Anonymous activist groups. 
 
 LulzSec has previously hacked the US Senate, the CIA, the NHS and an FBI partner company, as well as various games and entertainment companies. On Sunday, the group teamed up with distributed denial-of-service (DDoS) specialists Anonymous to launch an operation called AntiSec, or Anti-Security. 
 
 The first AntiSec victim appears to have been the UK's Serious Organised Crime Agency (Soca), which on Tuesday confirmed it came under DDoS attack on Monday. 
 
 The teenager arrested on Monday is currently in custody at a central London police station, where he is being held for questioning.
– British police have arrested a 19-year-old that they believe is involved with LulzSec’s recent wave of “AntiSec” digital attacks—though the group seems to be denying it. Investigators found the teen with help from the FBI, and have charged him under the Computer Misuse Act and the Fraud Act, ZDNet reports. But LulzSec’s official Twitter account chimed in, saying, “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?” Some tweets from LulzSec’s new ally, Anonymous, might shed some light on that. “The good news everybody: Ryan has little to do with #LulzSec besides running IRC,” one Anonymous member tweeted, according to Gizmodo. Another member identified the Ryan in question as Ryan Cleary, a hacker who last gained notoriety for, of all things, attacking Anonymous. Cleary lived in Wickford, Essex, the same location as the man arrested today. “If it is Ryan then they’re alright. lol,” another Anonymous member tweeted.
