The abduction of April Jones triggered the first nationwide child rescue alert ever used in the UK as investigators weighed up the risk to the child in the hours after her disappearance.
Late into Monday experts from the Child Exploitation and Online Protection unit, (Ceop) liaising with Dyfed-Powys police were engaged in the difficult decision of whether to initiate the high profile national alert to help in the hunt for the missing five-year-old.
A tactic long used in America, the child rescue alert has never been used across the country like this before, partly because suspected stranger abductions are rare.
Charlie Hedges manager of the missing, abducted and kidnapped children unit within Ceop said the decision to launch the alert was made in the knowledge that to do so could swamp the investigating team. Hedges said such alerts are usually only triggered if the police have detailed descriptions of suspects or vehicles to release to the public.
We discussed it long into the night," said Hedges. "Normally you would issue fairly precise information and we didn't have that. It was a really difficult call, but we decided the risk to April was such that we needed to launch the alert."
The child rescue alert a system adopted in the UK in 2010 aims to engage the public through the media and feed information back into the investigating team.
The special 0300 hotline number is answered by police forces across the country who are providing mutual aid to the inquiry and the information is fed into the major incident room within Dyfed-Powys police.
As every hour passes the risk to the child grows, something that will be at the forefront of the police's mind.
"The early hours are crucial in two ways," said Hedges. "From the point of view of the investigation, what has happened is fresh in people's minds and information coming in hasn't been contaminated.
"The other aspect is that the longer April is being held somewhere, the more damage there could be to her from a child protection point of view.
"Part of the appeal is trying to trigger people's consciences. Maybe there is someone out there who knows someone, or something about the person responsible."
