TalkTalk hack: Fifth person arrested over data theft

The furore over last month’s TalkTalk cybersecurity fiasco has died down a little, but investigations are ongoing.
Another individual has been arrested in connection with the alleged theft of TalkTalk customer data.
An 18-year-old became the fifth person to be detained by police as part of the investigation.
However, the male from Llanelli – not yet identified – has since been released on bail.
Four other people have been arrested, including:
- A 15-year-old from County Antrim
- A 16-year-old from London
- A 16-year-old from Norwich
- A 20-year-old from Staffordshire
All of those individuals were arrested on suspicion of offences under the Computer Misuse Act, although the latest arrest is related to a blackmail offence.

The investigation, which is being led by the Metropolitan Police Service’s Cyber Crime Unit, is looking into a security compromise that affected telecom provider TalkTalk in October.
According to the company, nearly 157,000 customers’ personal details were accessed, as well as 15,000 bank account numbers and sort codes.
However, TalkTalk maintains that the stolen bank details were incomplete.
