Former News International chief executive Rebekah Brooks has faced further police questioning after answering bail. The 43-year-old was questioned at Milton Keynes police station by officers from Operation Elveden, the Metropolitan Police said. She was re-bailed to return to a London police station in May. Operation Elveden is the Met's investigation into corrupt payments to police officers. Scotland Yard and Mrs Brooks's spokesman declined to comment, the BBC reports.   Mrs Brooks was last arrested on 13 March with six others as part of Operation Weeting, the Metropolitan Police's investigation into phone-hacking.
