The closing of two downtown clubs contributed greatly to a significant drop in crime last year, police said.Platinum Lounge, which was located near the intersection of South Walnut and Proctor streets, was shut down after a series of police incidents including the still-unsolved fatal shooting of a female patron. Primetime Lounge, which was located on Northside Drive West near Miller Street Extension, was closed after false information was discovered regarding the club’s alcohol license. The discovery followed the shooting of two men during business hours.
