Scotland Yard arrested a 31-year-old woman just before dawn today on suspicion of conspiring to intercept voicemail messages.
The Met said the unnamed woman was currently being held in custody at a police station in Northumbria.
"Officers from Operation Weeting have this morning, Wednesday, 30 November, arrested a woman in connection with conspiring to intercept communications," it said.
"At 0635 officers arrested the woman on suspicion of conspiracy to intercept voicemail messages, contrary to Section1 (1) Criminal Law Act 1977."
This is the 17th such arrest under the Weeting investigation. Charges are yet to be brought against anyone being probed by the Met on suspicion of phone-hacking. ®
