WALTHAM, MA - On June 18th, a report of a building fire at Sarris Auto Repair, 238 Calvary Street, sent Waltham Engine 3, Squad 5, Rescue 1 and Ladder 2 responding. Engine 1 and Medic 1 were dispatched as the RIT. Heavy black smoke was seen in the distance; however, it was not the building that was on fire, but a large truck that was fully involved. Deputy Tony Capello requested a working fire because of the many trucks next to the burning truck.  The fire was knocked down in about 20 minutes.
