Fayetteville police responded to a bomb threat early Wednesday morning at Walmart on Martin Luther King Jr. Boulevard.

An employee reportedly called police at around 4 a.m. to report that someone had written “At 4:15 a.m. this place blows up, I have a bomb” on a men’s bathroom wall.

Sgt. Craig Stout told a reporter that the public restroom was mostly used by Walmart employees.

According to several reports, employees and shoppers were evacuated from the building while officers searched the store and collected evidence. Everyone was allowed back in at around 6 a.m.
