A man has been arrested on suspicion of perverting the course of justice by detectives investigating allegations of phone-hacking.
The 46-year-old was held yesterday morning at his home address in south west London and was later questioned at a local police station, according to Scotland Yard said.
The suspect - who is not believed to be a journalist - is the 26th person to be arrested by officers working on Operation Weeting, the police investigation into claims that reporters hacked into mobile telephones to obtain stories.
A Scotland Yard spokesman said: "Detectives from Operation Weeting have this morning arrested a 46-year-old man at his home address in south west London on suspicion of perverting the course of justice.
"He has been taken into custody at a south London police station, where he remains."
Operation Weeting is running alongside two other investigations: Operation Tuleta, a Metropolitan Police inquiry into privacy breaches including the alleged hacking of computers and stolen mobile phones, and Operation Elveden, which is examining claims of corrupt payments to public officials.
