Using a data sample of 980  fb−1 of e+e− annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy e+e− collider, we report the results of a study of the decays of the Ω0c charmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the Ω0c into Ω−π+π0, Ω−π+π−π+, Ξ−K−π+π+, and Ξ0K−π+, as well as the first measurements of the branching fractions of the Ω0c into Ξ−¯K0π+, Ξ0¯K0, and Λ¯K0¯K0, all with respect to the Ω−π+ decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay Ω0c→Σ+K−K−π+.
