British police have arrested Rebekah Brooks, the former News International chief executive and a close aide of media mogul Rupert Murdoch, as part of an investigation into phone hacking and bribery by the defunct tabloid News of the World newspaper.
In Sunday's other major development related to phone hacking, London's police chief quit over his links to another ex-News International employee caught up in the scandal.
Paul Stephenson, the Metropolitan Police commissioner, has been criticised for hiring Neil Wallis, a former News of the World executive editor arrested last week, as a part-time public-relations consultant for a year until September 2010.
