Just after 11 a.m. today, township police received a call from an employee at Church & Dwight who opened an envelope and found an unknown white powder substance inside.
The worker was the sole employee at the company’s 100 Thanet Circle building to be exposed to the powder, police said. Princeton Township Police, the Princeton First Aid Squad and the Princeton Fire Dept responded along with the Trenton Fire Department’s HAZMAT unit to investigate the incident and attempt to identify the substance.
The New Jersey State Police, the FBI and the Dept. of Homeland Security were all notified of the incident. The powder was tested at the scene and preliminary results indicated the substance was powdered sugar. About 120 employees were isolated and quarantined as a precautionary measure while the tests were conducted, with no injuries reported.
Employees were allowed back in the building shortly after 1 p.m. A follow-up investigation is being conducted by the Princeton Township Police Department.
