The Molotov cocktail broke through a window of the home at the corner of 19th and Chestnut streets in Harrisburg on Mar. 3 around 4:20 a.m., the outlet reports citing the chief.
"Had it not been for that sprinkler system extinguishing the fire, we probably, without a doubt, would have had a much, much different outcome," the chief told the outlet.
No injuries were reported and the incident is under investigation.
