Greece activated the AMBER Alert HELLAS in September when a 5-year-old Nigerian boy disappeared from his cousin's apartment in Athens. The boy has Down syndrome and was staying with his cousin while his mother was hospitalized. The non-profit group Smile of the Child used the European Hotline Number for Missing Children to mobilize police in the area. A police investigation did not produce any leads, and authorities decided to issue the alert because of the time of night and the boy's medical condition. Because of the AMBER Alert, the child was found three hours later in a nearby building. He was visibly frightened but in good health.
