A white powdery substance sent to a government facility in Dallas early Tuesday morning has turned out to be non-toxic.
Dallas Fire-Rescue HazMat crews were called to 4141 N St. Augustine Road just after 6:30 a.m., after someone called to report a package with a white powder substance inside.
DFR says the powder appears to be non-toxic. The seven employees exposed were checked out by medics and have returned to work.
The Dallas Federal Bureau of Investigations (FBI) is still looking into the case.
