MARTA faces scrutiny after Beyoncé concert escalator mishap

• MARTA and Schindler, the escalator manufacturer, are investigating the incident, MARTA spokesperson Stephany Fisher said.

Catch up quick: The agency said MARTA Police on scene "reported that a person began screaming and running, causing a stampede on the escalator that caused it to temporarily speed up and then stop suddenly."

The other side: Jaylen Black, one of the injured concertgoers, told the AJC that more MARTA personnel should have been on the scene to handle the crowd.

• People were walking calmly, she told the outlet, "then all of a sudden it was free falling to the bottom." Black broke her ankle and leg and needed emergency surgery.

Zoom out: MARTA has faced increased scrutiny after service issues before the Peachtree Road Race and after Shakira's June 2 concert.

• The transit agency celebrated its performance moving FIFA Club World Cup crowds in May and June.
