Abstract: The recently observed IceCube PeV events could be due to heavy dark matter (DM) decay. In this paper, we propose a simple DM model with extra U(1) gauge symmetry and bridge it with standard model particles through heavy right-handed neutrino. The main decay channel turns out be three body and if the lifetime of DM is around 10^28 s, the spectrum from IceCube is well explained.
