A 15-year-old boy arrested in Northern Ireland in connection with the TalkTalk hacking attack has been released on bail.
The teenager was arrested on Monday afternoon on suspicion of Computer Misuse Act offences, the Metropolitan police said in a statement.
Officers from the Police Service of Northern Ireland (PSNI), working with detectives from the Metropolitan police's cyber crime unit, executed a search warrant at an address in County Antrim at around 4:20pm on Monday.
The boy was arrested at the address and taken to a local police station.
On Tuesday morning, police said he had been bailed to a date in November.
The Met's cyber crime unit launched an investigation into the attack on TalkTalk's website last week after it was revealed customers' information, including banking details, may have been accessed in the hack.
"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 21st October 2015," the company said.
"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."
