The incident occurred at around 2:30 a.m. Nov. 20.
A store clerk was told by one suspect to unlock the door and let him in. After briefly walking around the store, the first suspect then let in a second suspect, who was armed with a handgun and wearing a mask.
They ordered the clerk to lie on the ground, kicked her and proceeded to rob the 57-year-old of her personal belongings. They also took cash from the store register and beer.
Both suspects then left the business and were not seen getting into a vehicle.
The first suspect is described as a Hispanic male between 30 and 40 years old, standing between 5 feet 6 inches to 5 feet 7 inches tall, weighing around 200 pounds and has a dark moustache. The race of the second suspect is unknown. He wore a black long sleeve sweatshirt and long checkered shorts the night of the robbery.
Anyone with information about the crime or the suspects is asked to call the Riverside Police Department at (951) 353-7103.
