A man has been detained by the UK's Metropolitan Police in the first arrest made as part of an investigation into computer hacking by the press code-named 'Operation Tuleta'.
The 52-year-old was arrested in Milton Keynes on Thursday morning in connection with offences under the Computer Misuse Act.
Operation Tuleta was launched to investigate invasions of privacy by the British press that did not fall under the remit of Operation Weeting, the Met's probe into phone hacking by the News of the World and others, and Operation Elveden, its investigation into payments to police.
"Operation Tuleta is investigating a number of allegations regarding breach of privacy, received by the Met since January 2011, which fell outside the remit of Operation Weeting, including computer hacking," a statement from the Met reads.
The operation is said to include investigations into the use of Trojans sent via email that could have allowed hackers to take over a victim's computer.
