  An Oppenheimer-Snyder (OS)-type collapse is considered for a
Dvali-Gabadadze-Porrati (DGP) brane, whereas a Gauss-Bonnet (GB) term is
provided for the bulk. We study the combined effect of the DGP induced gravity
plus the GB curvature, regarding any modification of the general relativistic
OS dynamics. Our paper has a twofold objective. On the one hand, we investigate
the nature of singularities that may arise at the collapse end state. It is
shown that all dynamical scenarios for the contracting brane would end in one
of the following cases, depending on conditions imposed: either a central
shell-focusing singularity or what we designate as a "sudden collapse
singularity." On the other hand, we also study the deviations of the exterior
spacetime from the standard Schwarzschild geometry, which emerges in our
modified OS scenario. Our purpose is to investigate whether a black hole always
forms regarding this brane world model. We find situations where a naked
singularity emerges instead.
