The special characteristics of this black hole is that it is of \\emph{Petrov-Pirani type D} and the photon trajectories are \\emph{doubly degenerate principal null congruence}. We derive the conditions for existence of innermost stable circular orbit, marginally bound circular orbit and circular photon orbit in the background of Kerr-Newman-Taub-NUT(KNTN) space-time.
