Fear blankets the Postal Service's Bulk Mail Center in Northeast Philadelphia after a fired employee returned to the center and allegedly threatened to kill a supervisor.
The incident on Thursday night - the same day a fired postal worker gunned down co-workers in Michigan - set employees' nerves on edge and led postal authorities to ask for round-the-clock police protection at the center, 1900 Byberry Road.
Wallace Beckett, an acting superintendent, confirmed that an employee had been fired and that police were guarding the grounds, but declined further comment.
