The Port Authority of New York and New Jersey has filed a lawsuit claiming a steel company failed to deliver steel pieces needed to complete the antenna that will sit atop One World Trade Center.

The lawsuit filed Friday in Manhattan Supreme Court accuses ADF Steel Corp. of refusing to ship the remaining steel for the needle, which will be 408 feet tall when completed. The Port Authority says ADF has demanded about $6 million in payments for another project “as ransom” for shipping the rest of the steel.

ADF Steel had no immediate comment on Friday.

One World Trade Center is being constructed to replace the twin towers destroyed in the Sept. 11, 2001, terror attacks.
