Police announced around 2 p.m. the arrest of Thomas S. Greene, 59, in connection with the incident, citing multiple open warrants. Metro police said it was consulting with the U.S. Attorney’s office to determine if any charges would be brought Monday.
Metro’s Orange, Blue and Silver lines bypassed the Eastern Market station as the investigation continued, suspending train service between Federal Center SW station and Stadium-Armory. Metro Center station’s 12th and G Street entrance was also closed.
Metro Transit Police and DC Fire coordinated with a range of law enforcement agencies, including US Capitol Police and the FBI, Stessel said.
The FBI, multiple fire engines, ambulances, and two DC Fire Hazmat engines were on the scene Monday morning, along with three transit police vehicles, Metro SUVs, and a DC special operations environmental emergency response truck.
The situation eventually cleared, according to a Metropolitan Police Department officer. While the perimeter gradually reopened Eastern Market Metro Station remained closed. FBI personnel remained on the scene.
DC Fire and EMS tests found the powder at Eastern Market was “NOT hazardous” while Metro Transit Police tweeted that cleanup is underway. Train service will continue to bypass Eastern Market while the cleanup continues.
