A scheme to trace kidnapped children will be launched across the East of England on Monday.
The Child Rescue Alert system is an agreement between six police forces and the media to make public appeals for abducted children.
Managing directors have agreed to interrupt radio and TV shows to issue news flashes and run ticker messages.
Norfolk's Chief Constable Carole Howlett said the system could be the difference between life or death.
"Our hope is that we will never need to use this system and, thankfully, child abductions are extremely rare," she said.
"However, having this mechanism and agreement will mean that we are able to send out urgent messages and appeals very quickly if we need to.
"This could make the difference between a child living or dying."
The scheme is based on the US Amber Alert system and a handful of police forces across the country have already introduced the Child Rescue Alert system.
The six police forces involved are Norfolk, Suffolk, Essex, Cambridgeshire, Bedfordshire and Buckinghamshire.
