Abstract: Let $ G$ be a separable locally compact group containing a closed normal subgroup which is type I and regularly embedded. The elements of the dual space $ G$ are known to be induced from certain closed subgroups. In this article we first determine the kernel of an induced representation and then give necessary and sufficient conditions for $ G$ to be maximally almost periodic. These results are then applied to the collection of compact extensions of abelian groups.
