Phone Hacking: Rebekah Brooks Arrested Again
Five other people were detained, including Mrs Brooks’ husband, the racehorse trainer Charlie Brooks.
The arrests took place in Oxfordshire, London, Hampshire and Hertfordshire.
Police confirmed one woman and five men were held on suspicion of conspiracy to pervert the course of justice as part of the Operation Weeting hacking probe.
Former News of the World and Sun editor Mrs Brooks was arrested at her home in Oxfordshire. Her husband was also detained and they are now being held at separate police stations.
Officers are searching addresses connected to the arrests.
As well as Mrs and Mr Brooks, the other people arrested are a 39-year-old man from Hampshire, a 46-year-old man from west London, a 38-year-old man from Hertfordshire, and a 48-year-old man from east London.
Those held are being interviewed at police stations in Buckinghamshire, Oxfordshire and London.
Mrs Brooks was arrested under Operation Weeting last July on suspicion of conspiring to intercept communications, before being released on police bail. She has also been arrested as part of the Operation Elveden investigation on suspicion of corruption.
