Someone broke into a cellular phone store at 6537 Greenwell St. Tuesday and set fire to the business just before 4 a.m., District 6 Fire Chief Joel Hancock said.
No one was injured in the fire but Hancock said the business, Big Tyme Communications, is a total loss.
The call came in reporting the fire at 4:08 a.m., Hancock said.
Although the cellular phone store is one of four stores in the building, it was the only business to have major damage, Hancock said.
The other three businesses had some smoke damage.
Firefighters from District 6 worked with firefighters from the Central Fire Department and the Baton Rouge Fire Department to put out the blaze, Hancock said.
Hancock said his department will investigate the arson.
