According to reports, she will be quizzed by authorities over their investigation into Blake Fielder-Civil, who is now in remand at North London's Pentonville prision on suspicion of causing grievous bodily harm and conspiracy to pervert the course of justice.

The Mirror quoted a Scotland Yard source as saying: "We have no evidence against Amy being involved in any crime.

"If we had she would have been arrested straight away. But we do want to talk to her about matters, particularly financial ones, which may be important in this case."
