HERMISTON -- Police in Hermiston suspect a recent bomb threat at Walmart might be part of a scam popping up across the nation.
A suspect called the Hermiston Walmart on Monday afternoon and demanded $500 be put on GreenDot card or a bomb would go off inside the store, authorities said. The man had a foreign accent and stayed on the phone with an employee for about five minutes.
Police evacuated and searched the store but did not find any explosive devices.
Authorities say Hermiston could be the latest target of a bomb-threat scam that has happened across the country in the last year.

The FBI warned businesses nationwide about the scam earlier this year. Suspects typically call businesses and ask that $500 be placed onto the reloadable debit cards or a bomb will detonate.
No bomb has ever been found in the scams, authorities said.
