NEW YORK — The block of a crane crashed into the 12th floor of the partially-built 3 World Trade in Lower Manhattan Thursday night.

The block, which hangs by cable from the crane, crashed into the building located at 175 Greenwich St. about 8:35 p.m. The building is still under construction and is slated to open early 2018.

OEM initially said it was a wrecking ball, but sources told WPIX it was a block that was part of a crane at the construction site. Crews are working to dislodge it from the building.

The block hit a tempered glass window which is not in danger of falling, according to a source at the scene.

The building stands at the center of the new World Trade Center and is 80 stories high and 1,079 feet tall.
