Greencastle Fire Department responded to a fire in the back of DePauw maintenance pickup truck parked in between Roy O. West Library and the university heating plant along E. Larabee St. around 8 p.m. Tuesday.
The fire, which seemed to be contained within the bed of the grey Ford truck, was put out by at least five firemen quickly and with no incident.
Office Brad Williams of DePauw Public Safety, who was first on the scene, said the cause of the fire was unknown, although he suspects the source came from a toolbox in the bed of the truck.
Sophomores Dylan Sheldon and Matt Owen were driving to Phi Kappa Psi fraternity when they saw the flashing lights of the firetruck and then rising flames.
"We we're driving back, and we saw this gigantic fire," Sheldon said. "We both thought it was a dumpster at first."
