The dark photon, $A′$, the dark Higgs boson, $h′$, and the dark baryon, $B'$, are hypothetical constituents featured in a number of recently proposed Dark Sector Models. Dark Sector particles can be produced in the dark Higgs-strahlung and radiative processes, and in neutral $D$-meson decays channels. We will present results for the search of dark sector particles with prompt and displaced vertex decay topologies, when applicable, obtained using $1 {\rm ab}^{-1}$ of data collected by the Belle detector. We also report the results of a search for dark matter in radiative $\Upsilon(1S)$ decays.
