Zurich: 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).
UVEK said the poster was fake and it has launched an investigation.
"The federal government has nothing to do with this call and formally distances itself from it," UVEK said in a statement.
"There are neither such posters of the federal government nor corresponding requests, it is obviously a manipulation."
Several online users and experts have debunked the poster.
