FREMONT -- Police are investigating a bomb threat that took place over the weekend at a city Walmart.
The incident comes on the heels of another bomb threat that took place at a Walmart in Union City last week.
No one was injured in either incident and no devices were found during a search of the businesses.
Officers were called to the Walmart at 40580 Albrae Street on Saturday after a store employee dialed 911 and told dispatchers someone called and said there was a bomb inside, police Spokeswoman Geneva Bosques said.
Walmart evacuated the building until police arrived and checked the building for a bomb.
No threat or danger was found and employees and shoppers were allowed to reenter the building.
The week prior, on March 8, an anonymous bomb threat briefly shut down the Union Landing Walmart in the 30000 block of Dyer St.
During that incident, employees told police that the store received a bomb threat at about 5 p.m.
The building was evacuated and no threat or danger was found, police said.
Everyone inside the store was evacuated and a perimeter was set up around the parking lot.
Anyone with information about the threats is asked to call 510-286-6923 or 510-790-6957.
