The four-jet events collected by \delphi\ during the special LEP run at centre-of-mass energies of 130 and 136 \GeV\ in 1997 with an integrated luminosity of $5.9 \ipb $ are analysed. Their rate and the distributions of their di-jet masses, their smallest jet charges, and their di-jet charge separations all agree well with Standard Model predictions. Thus the hypothesis of pair production of a new particle with a sum of di-jet masses around $105 \GeVcc$ is not supported. The combined result of the four LEP collaborations refuting this hypothesis at over 99\% confidence level is also given
