British police have arrested another teenager allegedly affiliated with the Teampoison hacking group that last month hacked and published online recorded conversations between staff on Scotland Yard's anti-terrorist hotline.

The 17-year-old was arrested in Newcastle in connection with a series of high-profile cyber-attacks, Metropolitan Police said. In mid-April, officers arrested two youths aged 16 and 17 in the West Midlands in connection with the same incidents.

"The suspect, who is believed to use the online 'nic' [nickname] 'MLT', was alleged to be a member of and spokesperson for 'Teampoison'", Scotland Yard said.

"He has been taken to a local police station for interview. Computer equipment has been seized and is undergoing a detailed forensic examination."

The police added that Teampoison "has claimed responsibility for more than 1,400 offences" which include Distributed Denials of Service and "network intrusions where personal and private information has been illegally extracted from victims in the UK and around the world".

Targets included Facebook founder Mark Zuckerberg and the Facebook page of outgoing French president Nicholas Sarkozy

Mocking Scotland Yard and the MI6

The arrests relate to Teampoison posting a recording conversation on YouTube featuring two people discussing an alleged hack by 700 hoax calls to the hotline.

"We have been subjected to a barrage of calls from a group called Teampoison," says a voice. "We have had about 700 calls over the last couple of nights. One of the conversations I had last night was leaked on YouTube. Everyone else calling was effectively shut out and could not through at all."

Earlier last month, hackers affiliated with the group attacked MI6 in protest at what it said was the detention of innocent people on terrorism charges.

Teampoison is affiliated with many anti-US and anti-Israel hacking teams such as Mujahideen Hacking Unit and ZCompany Hacking Crew (ZHC).
