  In this paper, we consider the Klein-Gordon equation in a 3D charged rotating
hairy black hole background to study behavior of a massive scalar field. In the
general case we find periodic-like behavior for the scalar field which may be
vanishes at the black hole horizon or far from the black hole horizon. For the
special cases of non-rotating or near horizon approximation we find radial
solution of Klein-Gordon equation in terms of hypergeometric and Kummer
functions. Also for the case of uncharged black hole we find numerical solution
of the Klein-Gordon equation as periodic function which may enhanced out of the
black hole or vanish at horizon. We find allowed boundary conditions which
yield to the identical bosons described by scalar field.
