Police in Venice are investigating the source of a phosphorescent green liquid patch that appeared Sunday in the city's famed Grand Canal.
The governor of the Veneto region, Luca Zaia, posted a photo of the green liquid that spread through the water near the arched Rialto Bridge.
The patch was reported by residents.
Images on social media show a bright patch of green in the canal along an embankment lined with restaurants.
Zaia said that officials had requested that the police investigate to determine who was responsible.
Environmental authorities were also testing the water.
Venice's canals are one of the Italian city's most distinctive features.
And in the normal course of things, the water certainly doesn't look like a glass of cordial.
Earlier this year, some of Venice's secondary canals all but dried up due a prolonged spell of low tides linked to a lingering high-pressure weather system.
Venice is one of Italy's top tourist destinations, though its unique construction has sparked fears regions of the city may be less stable.
