A Harlem building that was under construction partially collapsed Monday afternoon, authorities say.
Police say the building on Saint Nicholas Avenue and West 125th Street was already in the process of being demolished before part of it collapsed at about 2 p.m.
No injuries were reported and all workers were accounted for. The scene has been blocked off as authorities respond.
The A, B, C and D subway lines run underneath the building, but MTA officials said trains slow down to 5 to 10 mph as they approach the 125th Street stop so it's not clear that subway vibrations contributed to the collapse.
The subway lines were running with delays for some time as investigators responded, but have since resumed normal service.
