Investigators in Salina and Great Bend are looking into bomb threats called in to local Walmarts.

The Salina store was evacuated after a threat was called in just after 3 p.m. Saturday. The scene was cleared about an hour later after officials found no credible threat.

A short time later, a second threat was called in to a Walmart in Great Bend. Several law enforcement agencies responded and evacuated as a precaution. Officers found nothing suspicious and cleared the scene.

Curtis Johnson and his family waited in the parking lot while investigators searched the building. His grandmother, Mary Hindman, worked at the Salina Walmart. He said she called them about the threat.

"She said the caller claimed there was a bomb in the building and it would explode in 15 minutes," Johnson said. "She called us and told us she loved us in case something happened."

Silmiar incidences were also reported in Woodland Park and Colorado Springs, Colo. stores.
