A 15-year-old boy who was arrested over an alleged cyber attack on TalkTalk has been released on bail, police in Northern Ireland have said.
He was held on suspicion of offences under the Computer Misuse Act, following a major breach of the telecoms firm’s website.
His home in County Antrim in Northern Ireland was also searched by detectives.
But a Police Service of Northern Ireland spokesman said that the teenager had been released pending further enquiries.
“The investigation being conducted by the Metropolitan Police Cyber Crime Unit, Police Service of Northern Ireland and National Crime Agency is continuing,” the spokesman said.
The company says it was forced to shut down its website after what it described as a “significant and sustained” cyber attack.
TalkTalk is urging its four million customers to check their accounts for any suspicious activity “over the next few months” and change their passwords.
However the company’s chief executive Dido Harding has said she was still unsure how many customers had been affected by the attack.
The breach is the third in a series of cyber attacks that have affected TalkTalk customers.
In August, the firm revealed its mobile sales site was hit by a “sophisticated and co-ordinated cyber attack” in which personal data was accessed.
In February, customers were warned about scammers who managed to steal thousands of account numbers and names from TalkTalk’s computers.
