  In this paper we study the Dirac quasinormal modes of an uncharged 2 + 1
black hole proposed by Mandal et. al and referred to as MSW black hole in this
work. The quasi- normal mode is studied using WKB approximation method. The
study shows that the imaginary part of quasinormal frequencies increases
indicating that the oscillations are damping and hence the black hole is stable
against Dirac perturbations.
