Abstract : Let $M$ be a compact almost coK\"{a}hler $5$-manifold with K\"{a}hler\-ian leaves. In this paper, we prove that $M$ is locally symmetric if and only if it is locally isometric to a Riemannian product of a unit circle $S^1$ and a locally symmetric compact K\"{a}hler $4$-manifold.
Keywords : almost coK\"{a}hler $5$-manifold, local symmetry
