A  Binghamton-area man was busted early Sunday after calling in a crank bomb threat to Trump Tower in Manhattan, according to police sources.

Stephen Williams, of Endicott, NY, allegedly called in the threat while at 355 Bowery, according to the sources.

A good Samaritan overheard the call, took a photo of the man and alerted cops, the sources said.

Williams was taken into custody while waiting for a bus at Port Authority, according to sources. Williams was in possession of duffel bags at some point but investigators determined they contained no explosives.
