In the framework of the minimal 5U(2)L X 5U(2h X U(l) theory, the possibility of large CP violating asymmetries in Bs decays is investigated. We show that a certain class of models where the CP symmetry is violated spontaneously and a relatively light We is allowed leads naturally to large CP asymmetries in the nonleptonic decays (~20%) and in the semileptonic decays (~20%) for a certain mass domain of We. The decay modes Bs~Ds*15s*, DsDs and
