  We consider the collapse of a charged radiation fluid in a Planck-suppressed
quadratic extension of General Relativity (GR) formulated \`{a} la Palatini. We
obtain exact analytical solutions that extend the charged Vaidya-type solution
of GR, which allows to explore in detail new physics at the Planck scale.
Starting from Minkowski space, we find that the collapsing fluid generates
wormholes supported by the electric field. We discuss the relevance of our
findings in relation to the quantum foam structure of space-time and the
meaning of curvature divergences in this theory.
