It is extraordinarily unusual, perhaps even unprecedented, for police to name and even issue a picture of a suspect in custody.
But there's a sense here now that these are desperate times and perhaps desperate measures are needed.
I understand Dyfed-Powys Police took legal advice before taking this decision and went ahead on the basis that issuing such an appeal could potentially generate lifesaving information.
I also understand that when Mark Bridger was arrested yesterday, police carried out a 'safety interview'.
Instead of taking him back to the police station to begin questioning, they asked him some very specific questions there and then before he'd had any legal advice: Do you know where April is? Is there anything you can tell us that could help safeguard her?
While not illegal, that too is unusual.
Detectives investigating the abduction of April Jones have until this afternoon to charge or release murder suspect Mark Bridger.
New photographs of missing five-year-old April Jones have been released by her family, as the search for her continues.
Police have been granted an additional 24 hours to question April Jones murder suspect Mark Bridger.
