Abstract
A radial deformation of the Kerr metric is studied which leads to the appearance of wormholes in certain cases. {\bf These wormholes can be thought of as being formed by two distinct but identical asymptotically non-flat spacetimes joined at the throat}. The status of energy conditions are discussed in details. The components of the energy-momentum tensor of the spacetime and its eigenvalues are explicitly given. It is shown that the resulting spacetime, represents a family of exact anisotropic fluid solutions.
