Townhouse arson attempt prevented by sprinkler system (Seattle, WA)

Investigators came to believe someone broke a window of a townhouse there and tossed an “incendiary device” inside, a police spokesman said in a statement. The device kindled a small fire, which was extinguished by the home’s sprinkler system.  A man and a woman inside the home at the time of the attack were not injured, the spokesman continued. Police do not believe it was a random attack.
