|Escalator going backwards|
(Scroll down for video) Several people were injured when an escalator suddenly started turning the opposite direction, according to video uploaded to the Internet.
A total of six people were injured when the packed escalator with rush-hour passengers suddenly changed direction at the Exchange Place PATH station in Jersey City, New Jersey, on Monday, sending riders falling and causing panic.
The Port Authority of New York and New Jersey, said that it was investigating what went wrong.
Passengers were traveling up from the train station platform on the escalator when it suddenly began to go down just before 9:00 a.m.
Michael Nochimson said that he jumped from the escalator as soon as it began to turn down.
"We were moving upward, then the escalator hesitated and began to slide back and gained speed. At that moment, I could see the panic and I could hear the screams of people behind me, so I knew I had to do something," he said.
Five people were taken to a hospital with injuries that are not considered life threatening, Port Authority spokesperson, Ron Marsico, said.
Part of the confusion was captured on video.
Nick Lukish said that he was heading to work and was halfway up the escalator when it started going down.
The 33-year-old man said that he saw a stampede of people at the base, while others climbed an adjacent ladder. Lukish said that he suffered cuts and bruises.
Exchange Place is open to travelers, but all services were suspended until Tuesday morning. The Port Authority also said that it was reviewing all its escalators throughout the system.
