Using the method of energy-level statistics, the localization properties of electrons moving in two dimensions in the presence of a perpendicular random magnetic field and additional random disorder potentials are investigated. For this model, extended states have recently been proposed to exist in the middle of the band. In contrast, from our calculations of the large-s behavior of the nearest neighbor level spacing distribution P(s) and from a finite size scaling analysis we find only localized states in the suggested energy and disorder range.
