The Plainsboro Police and Middlesex County Hazmat team were dispatched to Princeton University’s Plainsboro campus this morning to investigate a suspicious substance found in the mail services building.
The white powdery substance, which was mailed to a student at the university, turned out to be a food supplement powder.
The mail room is located at 701 Forrestal Road.
University Spokesman Martin Mbugua said this afternoon that operations are running normally.
