“The guy jumped. He broke through a couple of landings,” said a source with the city’s Office of Emergency Management, which had video of the 1:30 a.m. stunt gone awry.
A friend who lives in the building said Niu, a student at NYU’s prestigious Stern School of Business, “was barely moving” after his fall.
“[He] was definitely a little intoxicated and probably stumbled down,” the friend said.
Friends of the NYU TA said that he weighs roughly 150 pounds.
“I have no idea what kind of weight [the staircase is] supposed to sustain,” an OEM source said. “But, obviously, it was not being used normally. It was jumped on by a grown man from 10 to 12 feet in the air.”
Meanwhile, the missing sections of the stairwell stranded about 40 students on the roof. The student reportedly suffered broken ribs and a fractured ankle. Authorities are continuing to investigate the cause of the collapse, per the Post.
