An analysis of the decays of B ∓ → DK ∓ and B ∓ → Dπ ∓ is presented in which the D meson is reconstructed in the three-body final states K ∓ π ±π 0, π +π -π 0 and K +K -π 0. Using data from LHCb corresponding to an integrated luminosity of 3.0fb -1 of pp collisions, measurements of several CP observables are performed. First observations are obtained of the suppressed Atwood-Dunietz-Soni decay B ∓ → [π ∓ K ± π 0] Dπ ∓ and the quasi-Gronau-London-Wyler decay B ∓ → [K + K - π 0] Dπ ∓. The results are interpreted in the context of the unitarity triangle angle γ and related parameters.
