A fire at Betsy's Diner this morning at 457 Main Street in Falmouth appears to be electrical in nature and is not being considered suspicious. According to Deputy Fire Chief Scott Thrasher. Thrasher said that the first call came in just before 5 this morning and when crews arrived they saw smoke on the roof. The fire was quickly under control and considered out by 5:30. The building was unoccupied at the time and sustained some interior water damage but the fiore was limited to the roof.
