Detectives investigating phone hacking have arrested a 26-year-old man on suspicion of conspiracy to pervert the course of justice, Scotland Yard said.
The man was arrested at a residential address in Surrey earlier today and will be questioned at a London police station.
The arrest was made as part of the Operation Weeting investigation into hacking of voicemail boxes.
The man is the 24th person arrested as part of Operation Weeting. Six people - including former News International chief executive Rebekah Brooks and her racehorse trainer husband Charlie - have been charged in connection with the inquiry.
Mrs Brooks faces three charges of conspiring to pervert the course of justice, while her husband is charged with one count of the same offence.
The couple are due to enter pleas when they appear at Southwark Crown Court in London on September 26.
Fourteen others remain on bail pending further inquiries while four were released with no further action.
