A search for second and third generation scalar and vector leptoquarks produced in ep collisions via the lepton flavour violating processes ep → μX and ep → \tau X is performed by the H1 experiment at HERA. The full data sample taken at a centre-of-mass energy √s = 319 GeV is used for the analysis, corresponding to an integrated luminosity of 245 pb−1 of e+p and 166 pb−1 of e−p collision data. No evidence for the production of such leptoquarks is observed in the H1 data. Leptoquarks produced in e±p collisions with a coupling strength of lambda= 0.3 and decaying with the same coupling strength to a muon-quark pair or a tau-quark pair are excluded at 95% confidence level up to leptoquark masses of 712 GeV and 479 GeV, respectively.
