A 55 year-old man has been arrested in Cardiff in connection with Operation Tuleta, the investigation into computer hacking in relation to the UK phone-hacking scandal.
The man was arrested at his home on Friday morning at around 7am BST on suspicion of breaching the Computer Misuse Act (CMA) and the Regulation of Investigatory Powers Act (RIPA). He is in custody at a police station in the Cardiff area, the Metropolitan Police said in a statement.
The CMA covers hacking offences, while RIPA proscribes illegal interception of communications.
The UK phone-hacking scandal engulfed news organisations including News International, and catalysed the Leveson inquiry to examine UK press standards. The arrest on Friday was not directly linked to any news organisation, the police said.
