Suspicious Vehicle in NYC

A suspicious vehicle in Manhattan has led police to shut down Park Avenue between 47th and 57th Streets. The car is a black Mercedes whose trunk appeared weighted down; it had been parked there since 6 a.m. Thursday morning. Fox 5 News says police removed a suitcase from the car, which had traces of blood in it, and that it also contained a Koran. There were reports that some people had heard an explosion, but police say the sound was actually officers using tools to investigate the car.
