A top city official wasn’t fired because of his role in a controversial land deal that allowed a non-profit nursing home to be converted to luxury housing — but his boss refused to say Monday if he was ousted because of other federal investigations.

The axed official, Ricardo Morales, who served as a deputy commissioner at the Department of Citywide Administrative Services, was at the center of two deals now being probed by federal investigators.

One was the lifting of deed restrictions on Rivington House, a Lower East Side nursing home, that eventually led to its sale for luxury condos.
