SACRAMENTO (CBS13) — Authorities investigating a bomb threat at Sam’s Club in South Sacramento said no suspicious device was found and a search was underway for the person who handed a note to an employee saying there was a bomb in the store.

The Sacramento County Sheriff’s Office said a call to law enforcement came in at around 5:18 p.m. from an employee in the store. Investigators searched inside and outside of the building.

A description of the person who handed the note to the employee was not yet released.

“All of a sudden, a guy came up and said ‘Drop everything, we have a bomb threat,’ ” explained shopper Morris Stewart.

Morris Stewart was shopping with his son at the Sam’s Club on Power Inn Road Friday when dozens of customers and employees headed for the door.

“It’s not a joke, it’s not fun to mess with people’s lives and kid around like that,” said Stewart.

Evan Evangelista was working at the time when he says a fire alarm went off.

“It’s a waste of time, why are you going to do that right now? I’m trying to go home,” said Evangelista.

Employees waiting to get back inside took breaks getting food and then stood across the street while residents from nearby came by to witness bomb-sniffing dogs take over the store.

“It’s crazy because we would never expect this to happen. It’s April Fools, so it could be a joke, it could not be, but this is something serious,” explained neighbor Brian Loera.

More than two hours later, officials determined there was no explosive devices at the store.

They are investigating if April Fools Day has anything to do with the phony threat.

“We don’t know the age of this person, but again, it’s something we can’t discount that it is April Fools Day and it’s unfortunate that people are out here doing their daily activities and to be diverted like this and sacred,” explained Sacramento County Sheriff’s Office spokesperson Brian Loera.

Sam’s Club is located on Power Inn Road just off the Calvine Road exit off of Highway 99.
