LONDON, England (AP) — British authorities on Wednesday arrested a police officer and two journalists as part of the investigation into phone hacking by Rupert Murdoch's News Corp.

The 39-year-old police officer was arrested in Wiltshire in south-west England by officers investigating inappropriate payments to police and public officials. A 51-year-old journalist from Bristol and a 32-year-old journalist from London were also being questioned.

Police said late Wednesday that the three were bailed pending further questioning.

The corruption investigation was being run in conjunction with probes into phone hacking that followed revelations that reporters at Murdoch's now-shuttered News of the World tabloid routinely intercepted voicemails of those in the public eye.

Police say the arrests —bringing the number under investigation to 50 — came from information released by a News Corp. committee created to get to the bottom of the scandal.
