  For the Yang-Mills-type gauge-field theory with Lorentz symmetry group, we
propose and verify an explicit expression for the conserved currents in terms
of the energy-momentum tensor. A crucial ingredient is the assumption that the
gauge symmetry arises from the decomposition of a metric in terms of tetrad
variables. The currents exist under the weak condition that the energy-momentum
tensor and the Ricci tensor commute. We show how the conserved currents can be
used to obtain a composite theory of gravity and discuss the static isotropic
field around a point mass at rest.
