British police arrested two News of the World journalists today in the latest chapter of the British tabloid's ongoing phone-hacking scandal. In 2005 and 2006, News of the World hired a private investigator to illegally hack into the cell phone voicemail records of celebrities, politicians, and members of the royal family in an effort to generate scoops. The private investigator and News of the World's royal correspondent were sentenced to prison terms in 2007.

Now, The Guardian is reporting that the paper's former news editor, Ian Edmondson, and current chief reporter, Neville Thurlbeck, are in police custody for questioning. Documents seized from private investigator Glenn Mulcaire implicate the two men in the phone-hacking affair, but Edmondson and Thurlbeck both deny criminal wrongdoing and, as of now, don't face any charges.

Should Rupert Murdoch's News Corporation--which owns News of the World--be concerned that British police appear to be taking the phone-hacking investigation more seriously? The police don't appear to have "any evidence that would take the scandal higher up News Corp," The Guardian's Dan Sabbagh explains. But Murdoch shouldn't be sighing with relief, either. "Each arrest, each development in this long-running story, creates the possibility that new evidence may emerge." News Corp has said it will take action against employees convicted of wrongdoing.
