WHAT IS ROZ HUNTLEY GUILTY OF?

The charge sheet against the ice-cool Roz huntley grows longer every week and already includes murder, evidence tampering, wrongful arrest and perverting the course of justice.

Viewers have been led to believe that she killed forensics expert Tim Ifield during an altercation in his flat – and then tampered with blood samples to remove all trace of her DNA from the apartment.

The DCI also likes to frame people for crimes that she either can’t solve or she herself has committed.

So far she has set up Michael Farmer and abduction victim hana Reznikova for murder and has even placed her lawyer husband Nick (right, played by Lee Ingleby) under arrest.

But AC12 has a history of launching inquiries into corrupt officers who turn out not to be as bad as initially painted.

In previous series, the unit went gunning for Detective Inspector Lindsay Denton, played by Keeley hawes, only to discover she was a scapegoat for the crimes of underworld figures.

Is history about to repeat itself – and could there be more to huntley than meets the eye?
