A small part of East 65th Street between Lexington and Third Avenue caved in on Tuesday after what appeared to be a water main break.
The NYPD initially reported a partial collapse due to an underground steam pipe issue. A member of the New York City Council later told NBC 4 New York a broken water main was to blame.
Water seeping underground from the broken pipe caused part of the street to buckle.
Con Ed said there was no immediate impact to gas or electric service. About 450 customers were without water service, including a residential building and a parochial school, St. Vincent Ferrer.
