Last week, Metro Transit Police received a report from a rider about suspicious behavior at the L’Enfant Plaza station and on an Orange Line train to Vienna.

The rider told Metro he saw two men acting suspiciously and videotaping platforms, trains and riders.

“The men, according to the citizen report, were trying to be inconspicuous, holding the cameras at their sides,” Metro spokesman Steven Taubenkibel says.

The rider was able to photograph the men who were videotaping and sent the photo to Metro Transit Police.
