  We present a general analysis of the lepton polarizations in the rare Bs
->\gamma \ell^+ \ell^- decays by using the most general model independent form
of the effective Hamiltonian. The sensitivity of the longitudinal, transverse
and normal polarizations of final state leptons, as well as lepton-antilepton
combined asymmetries, on the new Wilson coefficients are investigated. It has
been shown that all these physical observables are very sensitive to the
existence of new physics beyond the standard model and their experimental
measurements can give valuable information about it.
