After 5 year old Ylenia was abducted and killed in 2007, there were calls to set up a Swiss alarm system that would be activated each time a child goes missing.
Under the new system, as soon as cantonal police receive a report of a suspected abduction, they will pass it to the Federal Police Office in Bern, which will then distribute the message via car radio announcements, motorway overhead electronic boards and loudspeakers at railway stations and airports.
