<dt>Description</dt>
<dd>Solutions of Einstein-Maxwell field equations suggest that charged black holes should exist. However, no physical process has been identified as to effectively violate the charge neutrality in a collapsing star. {\it In this essay} we demonstrate that such a process is possible in theories with an infinite extra dimension, where free massive particles localized on the brane can leak into the extra space. Because of color confinement only electrons, rather than protons, can escape. This leakage generates an electric charge asymmetry on initially neutral brane matter. Although the effect is quite small, it could be enhanced on large densities as in astrophysical objects. At the supernova collapse of a massive star, the residual charge in the imploding matter must be inherited by its remnant giving origin to a Reissner-Nordström black hole.</dd>
