Fire crews told Channel 9 that at least one person was displaced following an early morning house fire in north Charlotte. Firefighters were called just before 6:30 a.m. to the home on Maribel Avenue, near Lasalle Street and Beatties Ford Road. Officials said nobody was home when the fire started, but they did have to rescue a dog who was in its crate inside. The cause of the fire is still unknown but investigators believe it started outside, and police are investigating it as a possible arson.
