Fire causes heavy damage inside former Northeast Side Sonic restaurant

Arson investigators trying to figure out what caused fire

SAN ANTONIO – A fire that broke out early Wednesday has caused major damage to a former restaurant on the Northeast Side.

A passerby noticed the flames and smoke around 3:30 a.m. and called firefighters to the 4500 block of Rittiman Road.

They found fire coming out of the building, which used to house a Sonic fast food restaurant.

At one point, there were more than a dozen fire units at the scene, including a ladder truck.

Firefighters had to battle windy conditions to keep the fire from spreading to a gas station next door.

All of the damage was contained to the original site.

Firefighters say they did not find anyone inside the building.

They called in arson investigators to figure out how the fire started.
