SADDLE BROOK -- The Walmart on Route 46 was evacuated Tuesday afternoon when someone called the store to report a man on the roof with a bomb, according to northjersey.com.
"There's a guy named Jonathan on the roof with a bomb," the caller told a store employee, according to the report.
A search of the store proved the threat was unfounded and employees and customers were allowed in after about an hour, the report said.
