Narrative:

Approximately 7 mi northeast cvg airport on downwind we were cleared from 6000' to 4500' and told to look for traffic at 2 mi low going south. Second officer then pointed out other traffic at 12 O'clock, same altitude. First officer turned about 30 degrees to the left at about 20 degree bank and increased our rate of descent. We estimate passing within 400-500' vertical and horizontal of what was obviously an small aircraft. I asked the controller about the traffic and he said he had it on radar but asked us for its altitude. We estimated it at 6500'. The controller then advised our company flight who acknowledged seeing the small aircraft. Passenger did indicate upon deplaning that the small aircraft was quite visible from the cabin. No injuries occurred and no complaints were voiced.
