A 37-year-old woman was arrested today on suspicion of corruption as part of the Operation Elveden inquiry into allegations of inappropriate payments to public officials by journalists, Scotland Yard said.
In a statement the Metropolitan Police said they arrested the woman at Bromley Police Station.
She was arrested on appointment, on suspicion of conspiracy to corrupt under the Prevention of Corruption Act 1906.
Police also cited suspicion of conspiracy to cause misconduct in a public office, contrary to the Bribery Act 2010.
Scotland Yard said: "Today's arrest is the result of information provided to police by News Corporation's Management Standards Committee.
"It relates to suspected payments to a public official and is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately."
News Corp's management and standards committee is carrying out internal investigations relating to Rupert Murdoch's remaining UK papers - The Sun, The Times and The Sunday Times - and is working closely with the detectives investigating alleged phone-hacking and corrupt payments to police and other public officials.
A total of 30 people have now been arrested since last July as part of Elveden, which is linked to Scotland Yard's phone-hacking investigation Operation Weeting.
The development marks the first arrest by the force's phone-hacking squad since Rebekah Brooks and five other suspects were charged with conspiring to pervert the course of justice earlier this month.
A 50-year-old employee of HM Revenue and Customs was arrested along with a 43-year-old woman at an address in north-west London by Elveden officers that same day.
A News International spokeswoman confirmed the arrested woman is a current employee of the company.
In an internal memo to staff, News International chief executive Tom Mockridge said: "I am sorry to inform you that a further News International employee has been arrested by the police in connection with Operation Elveden.
"She attended Bromley Police Station by appointment at 9am this morning.
"As I have said before, it is important that proper due process takes its course and we must not prejudge the outcome of the police interviews.
"The company is continuing to do everything it can to assist our colleague, and has provided her with legal support.
"I appreciate this is difficult news for everyone and I am grateful for your continued hard work."
