Police in the Italian city of Venice have launched an investigation into why water in the city's central canal appears to have turned neon green.
The strange sight has been picked up by a number of Finnish media outlets as the colour is similar to that of the distinctive bolero jacket worn by Finland's entrant at this year's Eurovision Song Contest, the rapper Käärijä.
The Institute for the Languages of Finland (Kotus) announced last week that 'Käärijä-green' (Käärijänvihreä in Finnish) was its word of the month for May, as the colour appeared prominently on Finnish streets and social media in the run-up to the song contest final.
Initial reports from Italy suggest that the discolouring of the water could be due to the use of a dye by environmental activists. In 1968, Argentine artist Nicolas Garcia Uriburu dyed the water of the same canal green to draw attention to climate issues.
The fire brigade and the city's environmental agency have assisted the police's investigation by taking samples of the water for analysis.
