An extension of the standard model by at least one extra U(1) gauge symmetry has been investigated by many authors. In this paper we explore the possibility that this extra U(1) is anomalous. One possible signature of this model could be given by the photons produced in the decays of the next to lightest supersymmetric particle into the lightest supersymmetric particle.
