The unnamed 17-year old boy was arrested in the north of England on charges of violating the country's Computer Misuse Act 1990, which is the law in Britain typically used to charge people who are suspected of hacking offenses.
"The suspect, who is believed to use the online 'nic' 'MLT', is allegedly a member of and spokesperson for TeaMp0isoN ('TeamPoison')--a group which has claimed responsibility for more than 1,400 offences including denial of service and network intrusions where personal and private information has been illegally extracted from victims in the U.K. and around the world," read a statement released by London's Metropolitan Police Service. It said that the suspect had been tracked down by the force's Police Central eCrime Unit (PCeU), which serves as a cyber-crime investigation service for England, Wales, and Northern Ireland.

Police said they were interviewing the boy at a police station, conducting a forensic analysis of computer equipment seized as part of the arrest, and working to identify additional suspects. "Enquiries continue between the PCeU and other relevant law enforcement agencies in this continuing and wide-ranging investigation," said the Metropolitan Police.
MLT's arrest is not the first in the ongoing TeaMp0isoN investigation. Last month, two alleged members of the group--aged 16 and 17 years old--were arrested on charges of having used Skype to overwhelm Britain's anti-terrorism hotline with bogus calls. Their arrest came one day after a recording of one of the prank calls ended up on YouTube, with the headline, "TriCk calls Mi6 Anti-Terrorism Command - TeaMp0isoN."
In February, a hacker identifying himself as TriCk said that he was the 17-year-old British co-founder of TeaMp0isoN. Asked about his greatest accomplishment as a hacker, he replied, "My biggest achievement as a hacker is 'TeaMp0isoN' - embarrassing governments, corrupt organizations and corrupt individuals for 4+ years straight, and the 'enemy' STILL has nothing on us."
As that suggests, prank calls aside, TeaMp0isoN built its reputation by launching distributed denial-of-service attacks against numerous organizations, as well as "doxing"--obtaining and releasing sensitive information about--numerous businesses, government agencies, and individuals. Notably, the group last year published via Pastebin what it claimed to be Tony Blair's private address book. A spokesman for the former British prime minister said at the time that the information appeared to have been obtained from the personal email account of one of Blair's former staff members.
In January 2011, the group exploited a Facebook bug that allowed them to post bogus status updates to roughly 130 different Facebook pages, including pages for the social network's founder, Mark Zuckerberg, as well as then French president Nicholas Sarkozy.
More recently, TeaMp0isoN defaced and knocked the BlackBerry website offline during the August 2011 riots in England, and attacked the United Nations website in November 2011, leading to the release of various user IDs. That same month, TeaMp0isoN announced that it would be collaborating with Anonymous on the Operation Robin Hood wealth redistribution scheme.
Prior to that endeavor, however, the group's members had apparently not been fans of certain LulzSec and Anonymous elements, which they accused of having unsophisticated hacking techniques. In July 2011, TeaMp0isoN went so far as to release documents containing supposed personal information about members of the rival hacktivist crews, in an apparent effort to get the LulzSec and Anonymous participants arrested.
