Philadelphia police vigilant in the wake of the New York City attack

Philadelphia police say they're in direct contact with the NYPD and the FBI and there's no indication that this is part of a wider terrorist plot. There is also no information about any direct threats on Philadelphia.

Along the bike and running path on Kelly Drive Tuesday night, the terror attack in New York had people deeply concerned.

"I feel so susceptible when I am on this trail, walking just to the boathouse right down there and there's nothing to protect me," Brenton Molsbergen told FOX 29.

"I think it's an isolated incident. I think the city of Philadelphia is doing all they need to do to keep us safe," another runner said.

Runners and bikers took to the trails hours after the truck attack in New York City that left eight people dead and a dozen seriously injured in what New York authorities called an 'act of terror.'

"We will continue to be vigilant both protecting those soft targets as this one was the best that we can," Police Commissioner Richard Ross said.

"I hadn't even thought of that coming here, but I guess you have to keep your wits about you," Jim Ramsey said.

He and his wife, Ann, were out for a walk along Kelly Drive just after dark trying to fathom what the victims in New York were thinking as the Home Depot rental truck careened some four blocks, leaving victims in it's wake.

"It makes you on edge a little bit. Anything can happen, anywhere, at any time," Ramsey added.

Crowds still flocked to South Street on this Halloween night despite the attack in New York. At the Home Depot on Columbus Boulevard, rental trucks like the one used in the New York attack sat in the parking lot.

"Sadly, this is just one more thing that we have to pay attention to," Commissioner Ross also said .

Philadelphia police say they've urged their officers to be even more vigilant in the wake of the NYC attack and they're asking the public to do the same.
