Dane Fleary, who works at the Equinox gym down the block from the station, said a couple of his clients were forced to cancel their appointments with him because of the incident.

"It is what it is," he said. "It's dangerous. It's scary."

A woman who worked at the Sephora across the street said she was on her break when a lot of people came streaming into the store.
