  We study immersions of pointwise bi-slant submanifolds of locally conformal
K\"ahler manifolds as warped products. In particular, we establish
characterisation theorem for a pointwise bi-slant submanifold of a locally
conformal K\"ahler manifold to be immersed as a warped product and show that a
necessary condition is that the Lee vector field $B$ is orthogonal to the
second factor and the warping function $\lambda$ satisfies
$\text{grad}(\ln\lambda)=\frac{1}{2}B^T$, where $B^T$ denotes the tangential
part of the Lee vector field. We also extend Chen's inequality for the squared
length of the second fundamental form to our case and study the corresponding
equality case.
