Crane partially collapses, dangles over New York street

A crane atop a luxury Manhattan skyscraper under construction partly collapsed Monday, leaving its arm precariously perched and hanging over West 57th Street. New York police and fire crews are on the scene, and part of the street has been closed off as a precaution, according to Detective Martin Speechley of the New York Police Department.

The New York Office of Emergency Management is asking all occupants of upper floors in buildings near the site of the collapse to evacuate immediately to lower floors. One57, the skyscraper under construction, is offering some of the most expensive apartments in New York, with a penthouse there recently closing for more than $90 million, according to The New York Times.

New York City is experiencing high winds, with gusts up to 60 mph, but the cause of the collapse was not immediately clear.

The city's Department of Buildings on Sunday issued guidance that all cranes needed to be secured ahead of the brunt of Hurricane Sandy. It was not immediately clear whether that guidance was followed at One57.
