AB We report on measurements of the time-dependent CP violating observables in B  0s → D  ∓s K ± decays using a dataset corresponding to 1.0 fb−1 of pp collisions recorded with the LHCb detector. We find the CP violating observables C f = 0.53±0.25±0.04, A  ΔΓf = 0.37 ± 0.42 ± 0.20, AΔΓf¯=0.20±0.41±0.20, S f = −1.09±0.33±0.08, Sf¯=−0.36±0.34±0.08, where the uncertainties are statistical and systematic, respectively. Using these observables together with a recent measurement of the B  0s mixing phase −2β s leads to the first extraction of the CKM angle γ from B  0s → D  ∓s K ± decays, finding γ = (115 + 28− 43)° modulo 180° at 68% CL, where the error contains both statistical and systematic uncertainties.
