  By using the method of group analysis, we obtain a new exact evolving and
spherically symmetric solution of the Einstein-Cartan equations of motion,
corresponding to a space-time threaded with a three-form Kalb-Ramond field
strength. The solution describes in its more generic form, a space-time which
scalar curvature vanishes for large distances and for large time. In static
conditions, it reduces to a classical wormhole solution and to a exact solution
with a localized scalar field and a torsion kink, already reported in
literature. In the process we have found evidence towards the construction of
more new solutions.
