A recent paper [M. Kamata and T. Koikawa, Phys. Lett. {\bf B353} (1995) 196.]
claimed to obtain the charged version of the (2+1)-dimensional spinning BTZ
black hole solution by assuming a (anti-) self dual condition imposed on the
electric and magnetic fields. We point out that the angular momentum and mass
diverge at spatial infinity and as a consequence the solution is unphysicalComment: 4 pages, Latex, no figures, final version to be publised in Phys.
