AUGUSTA — Police in Augusta are investigating the thefts of eight large propane tanks in the city.

Six of the stolen 100-gallon tanks had been filled within the past week.

Two of the tanks were taken from the Children’s Discovery Museum. At least two other businesses were also hit, leaving them without heat as temperatures in the region start to fall.

The president of Augusta Fuel Company says he’s baffled by the thefts. Marc Lacasse tells the Kennebec Journal the stolen equipment was worth thousands of dollars and he doesn’t have the “slightest idea” how or why the thieves pulled off the heist.
