Police have arrested a 45-year-old woman as part of an investigation into computer hacking linked to a media phone-hack scandal.

The woman was arrested on suspicion of conspiracy to commit offences under sections one and three of the Computer Misuse Act, which deal with unauthorised access to computers, and sections one and two of the Regulation of Investigatory Powers Act, which concern the interception of data.

She was taken from her home in south-west London on Thursday morning as part of Operation Tuleta, the Metropolitan Police said in a statement on Thursday. Hers was the 18th Operation Tuleta arrest. The woman was questioned at a south London police station, and a search was carried out at her home.

Operation Tuleta is an inquiry into alleged computer hacking that is running in parallel to phone hacking investigation Operation Weeting. The two inquiries revolve around allegations of phone hacking by news media including journalists at the now-defunct Rupert Murdoch publication News of the World.

The woman's arrest was "not directly linked to any news organisation or the activities of journalists," said the police.
