The company was shut down for most of the day and hundreds of employees were sent home as police searched the facility for an explosive device after a threatening call was made around 7:45 a.m.
The North Carolina State Bureau of Investigation Bomb Squad found no suspicious devices during their search.
A criminal investigation is ongoing and anyone with information is asked to contact the New Bern Police Department.
