Update at 11:15 a.m. — The all-clear has been given and the scene is being cleared.
Earlier: Arlington County firefighters and Metro Transit Police are on the scene of a hazardous materials investigation at the Pentagon City Metro station.
Initial reports suggest a series of nearly a dozen soda bottles filled with a yellow-ish liquid were found on the platform. Authorities are trying to determine whether the liquid is hazardous.
The station is still open during the investigation, with only a portion of the platform closed to foot traffic.
“The station is open,” WMATA spokesman Dan Stessel tells ARLnow.com. “They’ve just cordoned off a portion of the platform. Trains continue to service the station normally.”
Stessel said authorities are “investigating unattended items.”
Metro Transit Police officers with bomb sniffing dogs could also be seen searching the area around the station entrance,
