Irish boy (15) arrested over TalkTalk cyber attack
A 15-year-old boy has been arrested in connection with the TalkTalk cyber attack.
The teenager was detained in Northern Ireland on suspicion of Computer Misuse Act offences, the Metropolitan Police said.
He has been taken into custody at a County Antrim police station where he will be interviewed later.
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 County 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 County Antrim police station where he will later be interviewed. A search of the address is ongoing and inquiries continue."
The investigation is being carried out by the Met's cyber crime unit, the PSNI's cyber crime centre and the National Crime Agency.
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."
Shares in TalkTalk fell more than 9% in morning trading and the firm has seen a fifth of its value wiped off in the last week alone.
TalkTalk is struggling to manage the fallout from last week's cyber attack in which huge amounts of customer data were stolen.
Chief executive Dido Harding has since revealed that criminals would not be able to access cash from affected customers' accounts as complete credit card details were not stored in its system and account passwords were not accessed.
She also warned of a "cyber security arms race" threatening all UK companies as she revealed she called in defence experts over the hack of its website.
TalkTalk chief executive Dido Harding said earlier she still was unsure how many of its four million UK customers had been affected by the attack, which had affected the telecoms giant's website rather than its "core systems".
