Metro suffered another escalator mishap Monday morning shortly after a video of an earlier failure went viral and appeared on CNN. This time an escalator at the Dupont Circle station jolted to a halt, causing riders to fall at about 9:20 a.m. Monday, according to one witness on Twitter. TBD.com first reported the incident. Metro spokeswoman Lisa Farbstein told The Washington Examiner that the problem appears to have stemmed from a handrail. The flaw triggered the emergency mechanism, causing the escalator to stop, she said.

She said no one was reported injured in Monday’s incident. A maintenance crew was dispatched to work on the issue, she said.
