Authorities say officers responded to a call of an armed robbery at the Target on Lone Tree Way around 2 p.m. Wednesday.
When officers arrived they found two suspects trying to drive away from the scene.
Another officer located a man who had been shot at the entrance to the store. He was taken to the hospital with non-life-threatening injuries.
A Target employee tells ABC7 that the good Samaritan was shot in the leg while trying to stop the robbers from getting away.
The suspects have been identified as Ramon Meza-Morales and Raul Garcia, both Antioch residents. Both were arrested and eventually booked into Martinez County Jail for armed robbery and assault with a deadly weapon.
