Metro Transit Police responded to the Pentagon City Metro station around the beginning of the evening rush hour for a “report of [a] suspicious package,” Metro said via Twitter.
According to Metro spokesman Mike Tolbert, a “suspicious note” was found on a train. The note was similar to another note — a bomb threat — that caused delays on the Blue, Silver and Orange lines this morning, Tolbert said.
Trains single tracked between the Pentagon City and National Airport stations for about a half hour as a result of the investigation. Metro said officers determined that the threat was “unfounded” and an all clear was given. Full service resumed, though with significant residual delays.
The incident even caused delays on the Green Line in D.C. “due to earlier congestion from delayed Yellow Line trains.”
