The 18-year-old teenager identified by police as the spokesman for the hacking groups Anonymous and Lulz Security has been charged with five computer security offences, and is expected to appear in a London court on Monday.

Jake Davis, 18, was arrested in the remote Shetland Islands last week. He is alleged by police to be "Topiary," a hacktivist spokesman who did interviews with media and ran a prolific Twitter account documenting frequent denial-of-service attacks and data theft escapades of Anonymous and LulzSec.

Hacking charges

Davis was charged with conspiring with others to conduct DDoS attacks against the website of the Serious Organised Crime Agency, a British law enforcement institution similar to the FBI. He is also charged with unauthorised access to a computer system, encouraging offences and two counts of conspiracy.

Davis is scheduled to appear in Westminster Magistrates Court on Monday where a judge will decide whether to remand him to custody or grant bail.

Also questioned last Wednesday, but not arrested, was a 17 year old male. The Daily Mail identified the teenager as the brother of Davis, although police on Monday said his name was not being released since he has not been charged and would not say if the two are related.

A police spokesman said Monday they were satisfied that Davis was "Topiary" and that they are not pursuing anyone else who uses the same handle. It has been suggested that the real Topiary is living in Sweden. Topiary's Twitter account has been inactive since July 22, when he wrote "You cannot arrest an idea."

Police campaign

Police have made several arrests of people allegedly involved with LulzSec and Anonymous, whose online campaigns have breached websites including SonyPictures.com, Fox.com and the Arizona Department of Public Safety computer network.

A 19 year old man, Ryan Cleary, was arrested on June 20 at his home in Wickford, Essex, for allegedly taking part in the attacks against SOCA. He is charged with five computer-related offences, and stands accused of distributing tools to build a botnet used to attack SOCA as well as websites of the International Federation of the Phonographic Industry and the British Phonographic Industry.

Last month, the Police Central e-Crime Unit also arrested a 16 year old, on suspicion of violating the Computer Misuse Act 1990.
