  Using N-body numerical simulations, we examine possible mechanisms for the
origin of the intracluster starlight features recently discovered in the Coma
cluster of galaxies. We show that tidal interactions of a ``normal'' elliptical
galaxy with a symmetrically distributed dark matter potential do not produce
the observed intracluster starlight features. A head-on collision of two normal
ellipticals does, however, explain the origin of the intracluster features with
surface brightness about 26 mag/arcsec$^2$). Another possible explanation for
the intracluster starlight features is galactic tidal interactions with massive
intracluster substructures. The presence of substructures in Coma with a
density of $\sim$ 0.1 times the density in the center of the galaxy, and with a
total mass about three orders of magnitude larger than the mass of a normal
elliptical galaxy, would account for the observations.
