A search for second and third generation scalar and vector leptoquarks produced in ep collisions via the lepton flavour violating processes e p → μ X and e p → τ 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 λ = 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.
