Federal and local authorities are looking for clues after a half-dozen cars were set fire in Philadelphia.
Police and an arson task force from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives said one of the apparent arsons yesterday damaged a house.
Authorities said a flammable liquid was poured near the driver’s side door of each vehicle in a northeast Philadelphia’s Bustleton neighborhood.
The first of the fires was reported shortly before 3:30 a.m. yesterday. Within an hour, five more blazes were reported or discovered by police within a one-mile radius.
No one was injured.
