We suggest that the anomalous 4-jet events recently reported by ALEPH may be the first indication of low scale technicolour. According to our interpretation about half of the events are due to resonantly enhanced pair production of charged technipions, of mass around 55 GeV, each decaying into a pair of jets, the other half being due to standard processes. The resonant enhancement is due to a nearby technirho resonance in the mass range 150-200 GeV, leading to hugely enhanced signals at the forthcoming LEP run at $\sqrt{s}=160$ GeV since the CM energy would be closer to the peak of the resonance.
