Traders, beware of eating Chinese food in front of the New York Stock Exchange. A 70-year-old security worker for the exchange owned by NYSE Euronext Group (NYSE: NYX) was hit by a truck while eating Chinese food in front of the exchange and died on the sidewalk Thursday.

"There's no way he could get out of the way, and that was it," bystander Aigne Goldsty said, according to AM New York. The man was eating his lunch at 1:30 p.m. outside of 45 Broad St. when a silver pickup truck belonging to T&M Protection Resources, which provides security services to the exchange, hit him.

Witnesses told AM New York that the man fell immediately to the ground after being hit by the truck and was twitching for about 20 seconds before ceasing to move.

"He just -- he collapsed. He was on the floor. They were trying to give him CPR. He lasted maybe 20 seconds, and I don't think he made it," Goldsby said, according to NBC New York. Goldsby said the victim was around 6 feet tall and 250 pounds.

The victim, also an employee of T&M, was later identified as Sorel Deps-Medina of Queens, according to NBC New York. In addition to Deps-Medina, two other people were hit by the truck: A woman, 31, and a man, 62, and were taken to a downtown hospital where they were in stable condition. The driver of the truck remained at the scene. The crash appears to have been an accident.

T&M Protection CEO Robert S. Tucker said that the company was "fully cooperating with the NYPD accident investigation. Our thoughts and prayers go out to the family of the victim," according to NBC New York.
