Cincinnati Police have made at least one arrest and now are looking for three more young black males who participated in a Wednesday night and Thursday morning crime spree. The dangerous behavior began Wednesday night when a Northern Kentucky man was carjacked while driving a white Toyota Corolla in Evanston. Several hours later a car matching the same description with 4 black males wearing ski masks inside robbed 4 people at gunpoint. The attacks occurred in Over The Rhine, Bond Hill, University Heights, and Mount Auburn between 1:30 and 8 a.m. Thursday morning. A gun was shown during each robbery but no one was shot or injured. Property was reportedly stolen. If you have information about the crime spree call CrimeStoppers at 513-352-3040.
