This dangerous situation inside a western Pennsylvania grocery store will require more than just a cleanup in aisle nine.

Instead, two grocery store bystanders were injured and a third is facing charges after a loaded gun fell from a man's fanny pack and discharged.

TribLive.com of Pittsburgh reports that Gerry Good, 58, of Gibsonia, Pa., was wearing a fanny pack at the local Giant Eagle when he leaned over inside the store and his gun fell out and discharged last Friday afternoon.

TribLive reports that the bullet hit the floor and pieces of what appeared to be ceramic tile struck and injured two people, identified as Ruth Preisser and Thomas Hornyak.

Both had minor leg injuries and were treated at the scene, police told the website.

Good was arrested and faces charges, according to Northern Regional police.

Good immediately told responding officers that it was his gun that fell and accidentally went off. The gun is registered to Good, who has a permit to carry the weapon, TribLive reported.

Giant Eagle spokesman Dick Roberts told TribLIVE: "We are relieved to hear that the customers sustained only minor injuries, received first aid in the store and were able to complete their shopping before leaving the store."
