Police in Oviedo, Spain, recently rescued three young children who had been isolated in a house for over three years by their parents, who seemed obsessed with keeping them from getting infected with the coronavirus.

People usually complain about nosy neighbors who can’t seem to mind their own business, but one woman in Oviedo, Spain, has been hailed as a hero after alerting police about unusual things going on in the house across the street from her property. The woman, referred to only as Silvia by Spanish media, had been keeping records about the activity in her neighbors’ house ever since they moved in, during the COVID pandemic. She had noticed that only the patriarch of the family was allowed to leave the house, mostly just to pick up groceries delivered at the front door, and that the family’s three kids only had their window blinds raised for short periods of time. However, the thing that prompted her to notify the authorities was the constant purchase of diapers, even though the children were eight and ten.
