"Officers on scene determined that a group of people ran through the mall, which caused alarm," police said in a tweet.
That's when multiple people called 911 "claiming a person had a gun and gun shots were heard," authorities added.
No shots were fired, police said.
"We will continue to investigate the false claims and hold those persons accountable."
On Tuesday, police released a photo of the possible suspect. He is described as a Hispanic man in his 30s. He was last seen wearing a white t-shirt, gray pants and black shoes.
The investigation remains ongoing.
The mall has since returned to normal operations.
