Teenager in North held over attack on TalkTalk
A 15-year-old boy has been arrested in the North in connection with the TalkTalk cyber attack.
The teenager was detained on suspicion of Computer Misuse Act offences, the London Metropolitan Police said last night.
He has been taken into custody at a Co Antrim police station, where he will be interviewed.
A Scotland Yard spokesman said: "An arrest has been made in connection with the investigation into alleged data theft from the TalkTalk website.
"At approximately 4.20pm, officers from the Police Service of Northern Ireland (PSNI), working with detectives from the Metropolitan Police Cyber Crime Unit, executed a search warrant at an address in Co Antrim, Northern Ireland.
"At the address, a 15-year-old boy was arrested on suspicion of Computer Misuse Act offences.
"He has been taken into custody at a Co Antrim police station, where he will later be interviewed. A search of the address is ongoing and inquiries continue."
The joint investigation is being carried out by the Met's cyber crime unit, the PSNI's cyber crime centre and the UK's National Crime Agency.
Following the arrest, a TalkTalk spokesman said: "TalkTalk can confirm that we have been informed by the Metropolitan Police of the arrest of a suspect in connection with the cyber attack on our website on October 21.
"We know this has been a worrying time for customers and we are grateful for the swift response and hard work of the police. We will continue to assist in the ongoing investigation."
TalkTalk chief executive Dido Harding had said earlier that she was still unsure how many of its four million British customers had been affected by the attack, which hit the telecoms giant's website, rather than its "core systems".
Jesse Norman, chairman of the UK's Culture, Media and Sport Select Committee in Parliament, is leading a separate inquiry into the alleged breach.
Officers are investigating a ransom demand sent to the phone and broadband provider by someone claiming to be responsible and seeking payment.
The firm said it was not sure if the message was genuine.
The latest breach is the third in a spate of cyber attacks affecting TalkTalk in the last eight months. Previous incidents in August and February resulted in customers' data being stolen.
TalkTalk saw more than a tenth of its value wiped off in trading yesterday as shares plummeted more than 12pc, adding to the 4.3pc drop it suffered last Friday.
