[UPDATE BELOW] An unidentified man is in critical condition after being struck by a National Guard vehicle this afternoon. Witness Tim Coleman was working as a PA for a film shoot near the intersection of Canal and Centre streets at around 1:24 p.m. and noticed a "convoy" of National Guard vehicles driving west down Canal. "I was talking to two people on the street, when out of the corner of my eye stuff starts flying into the air," Coleman tells us. "I see a guy on the ground, most of his body is under the truck, and blood starts pooling out of the back of his head. I realized, 'Oh, God, the stuff that was in the air was the man's bags.' "

Coleman added that the National Guardsman jumped out of their vehicles "immediately" to aid the man, and that police and paramedics arrived "not even a minute" later to perform CPR. The FDNY confirms that the victim was transported to Bellevue Hospital and that his injuries were life-threatening. The National Guard's public affairs office has not yet returned requests for comment, and the NYPD's press office is looking into the matter. We'll update when more information becomes available.

[UPDATE / 4:59 PM] Though an NYPD spokesman tells us, "My understanding is that the victim is still alive," J. David Goodman of the New York Times as well as The Daily News are reporting that the victim, an 82-year-old man, has died.

A witness told The Daily News that the truck was racing to make the light when it struck the unidentified man: “It’s the driver’s fault. He tried to catch up and that’s when he hit him.”

[UPDATE 2] The NYPD has identified the victim as Queens resident Kwok Fu.
