Three people were injured this morning after a window popped out of a midtown high rise, sending shards of glass raining down onto the street below. The FDNY tells us the incident occurred at approximately 8:45 a.m. at 40 West 57th Street. Three people were injured. One of the injured pedestrians refused medical attention, but two others were taken to Roosevelt Hospital with minor injuries.

The broken glass reportedly burst out of the 18th floor. 1010WINS reports that "someone working inside the building fell into the window" and "the window then popped out and fell to the street." The building's tenants include Northern Trust, JPMorgan/Highbridge, and Two Creeks Capital Management LP, a boutique financial company.

The stretch of 57th Street between Fifth and Sixth Avenue was temporarily closed to pedestrians and motorists, but the north side of the street has reopened while the south side was still closed as workers sweep up the glass.

Many pedestrians on the sidewalks were office workers who were headed to their buildings on the block. One woman, who works at 50 West 57th, the neighboring building, muttered, "I guess it's good I didn't take an earlier bus or else I might have been hit." And one anxious man asked a police officer why the whole street was shut down.

The cop, one Officer Allison, wryly said, "Come on, it's New York City! You know you're going to be inconvenienced."

We'll update with more information as it becomes available. In the meantime, please remember that it's never safe to go anywhere or do anything.

Update 12:14 p.m.: A spokesperson for LeFrak, which owns the building, issued a statement saying, "We are continuing to investigate the situation and are cooperating fully with the authorities."

Update 2 p.m.: Apparently 50-60 pounds of glass may have fallen from the window. WCBS reports, "Witnesses said a tourist from North Carolina stumbled into a cafe and was bleeding after a piece of glass struck her head... The woman and a construction worker who was inside the building were rushed to the hospital. Another pedestrian also sustained a minor injury."
