NEPTUNE BEACH, Fla. -- Fire crews say a faulty AC unit may have caused an early morning fire at a popular pizzeria Thursday.

Authorities say the fire started just before 4 a.m. at Ray's Pizza on Third Street.

Firefighters were able to put out the flames before it expanded to the rest of the building.

The owners are not sure when the damage will be repaired and when they will be able to reopen.

No one was injured.
