It was mass hysteria Friday evening at Penn Station with thousands of people running in every direction, leaving behind their shoes, luggage, and other valuables fearing the absolute worst.
Panicked screams were followed by a stampede of travelers at Penn Station Friday during the peak of the rush hour commute, when Amtrak police attempted to detain two men for disobeying orders.
"They were trying to calm down that man," an eyewitness said.
Eyewitness News' cameras were there as transit police used a Taser on one of the men. He managed to get away from officers, but was tackled moments later.

In the midst of the chaos, some people overheard there was an active shooter in the terminal sparking a frenzied domino effect all the way to the NJ Transit terminal.

The NYPD received over two dozen 911 calls about an active shooter, with the mayhem extending more than a block away to stores along 34th Street including Macy's which was briefly evacuated.
