  Searches for rare processes such as mu --> e gamma put stringent limits on
lepton flavour violation expected in many Beyond the Standard Model physics
scenarios. This usually precludes the observation of flavour violation at high
energy colliders such as the LHC. We here discuss a scenario where right-handed
neutrinos are produced via a Z' portal but which can only decay via small
flavour violating couplings. Consequently, the process rate is unsuppressed by
the small couplings and can be visible despite unobservably small mu --> e
gamma rates.
