A Midtown Manhattan building, which formerly housed Pfizer offices and is being converted into apartments, and several nearby buildings were evacuated Tuesday morning after officials discovered support columns were buckling, sparking fears it may collapse.

The New York Fire Department said it received a call shortly before 8 a.m. EDT saying bricks were spotted falling from the 21st floor of the building, multiple outlets reported, where officials then discovered two support columns were buckling.

The building, as well as several nearby buildings, were evacuated Tuesday morning, while surrounding streets were closed.

No injuries have been reported, fire officials said.

Metro Loft Management, a real estate agency leading the building’s conversion, told Bloomberg in a statement it is “aware of what happened and are working closely with the Department of Buildings to understand the full scope of the situation.”
