Grocery store shoppers were smoked out of a Hillcrest Ralph's Supermarket when someone lit toilet paper on fire Friday afternoon.
Nearly $10,000 worth of damage was done when the suspect started the fire in the store's Aisle 13 at 1030 University Avenue, according to the San Diego Fire-Rescue Department.
Firefighters were able to contain the flames before they spread to the rest of the building.
They say the fire burned about $1,000 in structural damage and $9,000 worth of store merchandise.
Arson investigators are reviewing surveillance video to try to identify the suspect.
No one has been taken into custody.
