Swiss authorities have launched an investigation into fake online images of posters calling on citizens to report neighbours for over-heating their homes, which one expert said could have links to Russian disinformation campaigns.
Images have circulated on social media showing what was supposed to be a poster featuring a young woman on a phone and the question: "Does your neighbour have their heating set at more than 19C? Please contact us."
A reward of 200 Swiss francs ($207) for information is offered in the image, which also features the Swiss government's logo and a telephone number for the Department of Environment, Transport, Energy and Communication (UVEK).
