British police searched the offices of Rupert Murdoch's British newspapers Saturday after arresting a police officer and four current and former staff of his tabloid The Sun as part of an investigation into police bribery by journalists.

The arrests spread the scandal over tabloid wrongdoing — which has already shut down one paper, the News of the World — to a second Murdoch newspaper.

London's Metropolitan Police said two men aged 48 and one aged 56 were arrested on suspicion of corruption early in the morning at homes in and around London. A 42-year-old man was detained later at a London police station.
