Venice authorities were left puzzled on Sunday after a section of the Grand Canal near the Rialto Bridge turned a fluorescent green.
The mysterious incident was reported to police at around 09.30 on Sunday morning, with tests carried out by experts from the fire service and the regional environmental protection agency ARPAV.
In a press release, Venice police said the discoloration appears to be from a “tracer dye”, commonly used to detect leaks and monitor water flows, however the source of the liquid remains unknown.
