The United Kingdom relaunched a new and improved Child Rescue Alert to help find abducted children. The original system was launched in 2004 and is based on the U.S. AMBER Alert Program. The new system will use computer software to send messages to radio, television, cell phones, computers and roadway signs. The program is also compatible with alerts used by other European countries. The Child Rescue Alert Program is being overseen by the National Policing Improvement Agency (NPIA). "Child Rescue Alert is not expected to be used often, as strict criteria must be met, but it is a valuable tool available to a senior investigator to be used in the right situations," said NPIA Chief Constable Peter Neyroud.
