The Layton Hills Mall was closed for three hours Monday as police and FBI agents unsuccessfully searched the stores for a man who held up a nearby bank and then fled into the mall.

The man robbed the First National Bank on the mall's perimeter about 9:55 a.m., and witnesses told the Layton police they saw him run into the mall. Police cordoned off the 70-store mall around its outer perimeter road.Shoppers and store employees left, with police searching their vehicles and then turning their attention to the mall itself. Teams of police and FBI agents swept through the mall for more than two hours but did not find the robber.

Shortly after 1 p.m., the search was given up and the mall allowed to reopen.

The FBI said the robber gave the impression that he was armed but no weapon was seen.

The robber is described as a white male, 27 to 32 years old, 5 feet 10 inches tall, and stocky, weighing around 190 pounds. He is described as having a rough, ruddy complexion, long dark brown hair and a post earring in his left ear.

The robber was wearing blue jeans, a blue nylon quilted jacket with a fleece collar and a gray stocking cap, police said.
