Abstract
We discuss the recently observed excess of high Q2 neutral current deep inelastic scattering events at HERA in the light of supersymmetry with broken R-parity. We find more than one possible solution. We consider the possibilities for testing these hypotheses at HERA, the TEVATRON and at LEP. One lepton-number violating operator can account for both the HERA data and the four-jet anomaly seen by ALEPH at LEP.

Comments
In our original manuscript we made a mistake in the cross-section computation. The correction has lead to changes in the allowed solutions. Also corrected typos in the Appendix. 29 pages, 6 figures
