Using a data sample of 980 fb^-1 collected with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider, we study for the first time the singly Cabibbo-suppressed decays Ω⁰_c → Ξ¯π⁺ and Ω¯K⁺ and the doubly Cabibbo-suppressed decay Ω⁰_c → Ξ¯ K⁺. Evidence for an Ω⁰_c signal in the Ω⁰_c → Ξ¯π⁺ mode is reported with a significance of 4.5σ including systematic uncertainties.
