If so they'd be duty bound to release the image of, what is, a very dangerous man, whilst warning the public not to approach him.
In order to describe (they've said he's white) their latest suspect, they must have CCTV or such footage/images of said latest suspect. So why aren't they releasing it, and advising people not to approach him?
One wonders if the outcome of this will involve yet another example of the police having to refer themselves to the watchdog.
