A suspicious substance found in Amtrak's main office in Washington, D.C., drew nearly a dozen emergency vehicles to Union Station on Friday morning, but it turned out to be nothing more than a scare.
D.C. Fire and EMS responded to the scene at 10:58 a.m., according to Fire Department spokesman Oscar Mendez, and a hazardous materials unit began investigating. Police were also on the scene and officers with K-9 units stood on guard outside gates to the train tracks.
Trains appeared to be operating as usual inside the station Friday morning, but outside traffic was crawling around Columbus Circle. Capitol Police warned people to avoid the area shortly before noon, throwing some lunch plans into flux around the Capitol community.
Kimberly Wood, a spokeswoman for Amtrak, said in an email that first responders were "investigating an unknown substance found on the premises" and directed further questions to D.C. Fire and EMS.
By 12:30 p.m., ambulances were starting to pull away from the scene. Mendez confirmed that nothing hazardous had been found.
