A man has been arrested by officers working on Operation Tuleta, a police investigation into computer hacking and other breaches of privacy connected with the phone-hacking scandal.
The Metropolitan Police said on Thursday that the 52-year-old man had been arrested in Milton Keynes on suspicion of Computer Misuse Act offences. The arrested man is in custody at a Thames Valley Police station.
Operation Tuleta was set up earlier this year to deal with certain aspects of the News International phone-hacking affair that are not covered by Operation Weeting. These include allegations of private investigators hacking, on behalf of the media, into the emails and files of celebrities and politicians.
Former prime minister Gordon Brown claimed in July that News International journalists had used Trojans to gather information about their targets.
