BATON ROUGE - Fire investigators are working to determine the cause of a fire at a Baton Rouge apartment complex early Wednesday morning.

Baton Rouge firefighters were called to the scene at the Hawthorne Heights apartment complex just after 4:30 a.m. The apartments are located in the 2100 block of North Lobdell Avenue.

According to BRFD, the apartment office was already engulfed in flames by the time firefighters arrived. The fire was quickly put out before it could spread to other units in the complex. The fire was under control by 5:09 a.m.

Firefighters said four families were displaced due to smoke damage to their apartment units. No injuries were reported.

Apartment complex administration is working to place the displaced families in other living quarters.

Damage to the apartment complex is estimated at $75,000. The investigation is ongoing, but foul play is not suspected as of Wednesday morning.
