We investigate systematically how to extract new physics contributions in B --> K pi l^+ l^- decay by using the angular decomposition. The decomposition will enable us to define not only several CP averaged forward-backward (FB) asymmetries but also the direct CP asymmetry and the time-dependent mixing induced CP asymmetry for each FB asymmetry newly defined in the general 4 body angular space. The decay process involves several intermediate vector and scalar resonances as sources of strong phase difference through interference, therefore, one can expect largely enhanced CP asymmetries, if there exists any new physics with weak CP phases. The combined analysis of the FB and CP asymmetries will give us fruitful information about new physics contributions in detail.
