Authorities say a bomb threat prompted the evacuation of a Secaucus Wal-Mart store, but no explosive devices were found at the business.

The Hudson County Sheriff's office says roughly 700 customers and employees were evacuated from the store in Secaucus after the threat was received around 2 p.m. Monday. It's located in the Harmon Meadow Cove shopping plaza.

Authorities believe the New Jersey call is related to at least a dozen similar threats that have been received at Wal-Marts in Kansas, Oklahoma and Missouri in recent days. No explosives were found in those incidents.
