Search for pair-produced Leptoquarks in e+e-                                   
collisions at sqrt(s) = 183 GeV                                                
  
A search for pair-produced leptoquarks                                         
has been performed using a sample of e+e-                                      
collision events collected by the OPAL detector at LEP at                      
centre-of-mass energies of about 183~GeV.                                      
The data sample corresponds to an integrated luminosity of                     
55.9 inverse pico-barns.                                                       
The leptoquarks were assumed to be produced via couplings                      
to the photon and the Z and then to decay within a single fermion              
generation.                                                                    
No evidence for contributions from leptoquark pair production processes        
was observed.                                                                  
Lower limits on scalar and vector leptoquark masses are obtained.              
The existing limits are improved in the region of large decay branching        
ratio to quark-neutrino.
