The conformal symmetries of a free scalar field can be extended to infinite dimensional higher-spin(HS) symmetries. We consider the gauging of the symmetries by HS gauge fields, and compute the corresponding HS effective action. The latter exhibits an anomaly in the conformal sector of the HS symmetries. We also discuss holographic aspects of the model as the boundary dual of an interacting HS gauge theory in the bulk.
