Using e+e- annihilation data collected by the CLEO II detector at CESR we have observed the decay D+s→ωΠ. This final state may be produced through the annihilation decay of the D+s or through final state interactions. We find a branching ratio of γD+s→ωΠ/D+s→ηΠ=0.16α0.04±0.03 where the first error is statistical and the second is systematic.
