The process e+e- --> llBARffBAR, where 1 is a charged or a neutral lepton and f any charged fermion, is analyzed. The study uses the ALEPH data collected at LEP from 1989 to 1993 at centre-of-mass energies between 88 and 95 GeV, corresponding to almost two million hadronic Z decays and to a total integrated luminosity of 79 pb-1. For all channels, the data agree well with the standard model expectation both in shape and normalization. The indication of an excess in the e+e- --> tau+ tau- ffBAR channel, reported by ALEPH in 1991, is not confirmed
