We study the charged lepton flavour violation in a popular neutrino massmodel with $A_4$ discrete symmetry. This symmetry requires the presence ofmultiple Higgs doublets in the model and it also dictates the flavour violatingYukawa couplings of the additional neutral scalars of the model. Such couplingslead to the decays of the neutral mesons, the top quark and the $\tau$ leptoninto charged leptons of different flavours at tree level. The $A_4$ symmetry ofthe model leads to certain characteristic signatures in these decays. Wediscuss these signatures and predict the rates for the most favourable chargedlepton flavour violating modes.
