An early morning fire Monday at Northridge Fashion Center was extinguished by the mall's sprinkler system before it could spread, according to authorities.
The fire occurred just after 6 a.m. in the Natural Wonders store, said Brian Humphrey, a L.A. Fire Department spokesman.
The flames were out when firefighters arrived; the cause of the fire remained under investigation.
Investigators estimated Natural Wonders had lost $1,500 in property. But the figure could grow because of un-tallied smoke and water damage.
Firefighters spent about an hour ventilating the entire mall, Humphrey said. Except for Natural Wonders, the rest of the mall opened on time.
