After investigation, police determined the package did not contain a bomb, according to authorities
Asato said that someone called Metro Transit Police, reporting that there was a bomb in a package at the Arlington station.
Trains were turning around on either side of Pentagon City on the blue and yellow lines, as a result.
Metro also set up shuttle bus service between L'Enfant Plaza and Crystal City and between Arlington Cemetery and Crystal City.
Asato says Metro resumed normal service around 7:40 p.m. Riders may still experience some delays because of the large crowds at the cherry blossom festival and attending a Washington Nationals game.
