Fashion Valley Mall was closed at 9 p.m. Friday night after an attempted robbery at the Kay Jewelers store, according to police.
Officials say a man armed with a handgun confronted four employees as they left the jewelry store for the night. One employee was holding a bag, which the suspect took.
The man fled the scene and was last seen running north out of the mall.
Police say the sack did not contain any money, and there was no loss from the store. No injuries were reported.
Officials described the armed suspect as a black man in his 20s with a thin build. He was wearing a black hooded sweatshirt at the time of the incident.
