  We study the holographic currents associated to Chern-Simons theories. We
start with an example in three dimensions and find the holographic
representations of vector and chiral currents reproducing the correct
expression for the chiral anomaly. In five dimensions, Chern-Simons theory for
AdS group describes first order gravity and we show that there exists a gauge
fixing leading to a finite Fefferman-Graham expansion. We derive the
corresponding holographic currents, namely, the stress tensor and spin current
which couple to the metric and torsional degrees of freedom at the boundary,
respectively. We obtain the correct Ward identities for these currents by
looking at the bulk constraint equations.
