People drinking on Spalding’s Coronation Channel riverbank are being told to clean up after a fire caused by sun rays reflecting off a beer can.
Firemen from Spalding used a hose reel jet to put out the blaze on the riverbank off Low Road just after 2pm last Tuesday.
A Lincolnshire Fire and Rescue spokeswoman said: “The fire was not started deliberately but caused by sun rays magnifying from a beer can onto cut grass.
“This is a reminder as to the importance of clearing up and putting bottles and cans in the bin.”
