A police helicopter flew above Deventer for a large part of the evening. This had to do with an ‘urgent missing person’, a spokesman said. Help from Burgernet has not (yet) been called in. The helicopter first flew above the Keizerslanden district, then above the city center, among other things. Police have not provided any details regarding the disappearance. When help from residents of Deventer is needed, Burgernet may still be called in.
