FORMER News International chief executive Rebekah Brooks was today questioned about payments to Ministry of Defence officials.
The ex-News of the World and Sun editor has been bailed until May after facing questions relating to Metropolitan Police Operations Elveden and Weeting.
Mrs Brooks was originally arrested in July 2011 on suspicion of conspiring to intercept communications and on suspicion of corruption allegations.
She was arrested for a second time on March 13 this year on suspicion of conspiring to pervert the course of justice.
The 43-year-old arrived in Milton Keynes in a black BMW, chauffeured by an unknown male driver, at 10am this morning. She faced seven hours of questioning before eventually being released.
Operation Eleveden is an investigation into allegations of inappropriate payments to police, while Weeting is looking into the phone hacking scandal.
The Met confirmed that a 43-year-old woman has been released on bail until May.
