Police are cautioning South Side residents after a pair of robberies last month in the Kenwood and Bronzeville neighborhoods.
In both robberies, two men walked up to victims, threatened to hurt them and stole their property, according to an alert from Chicago Police.
The first happened about 8 p.m. July 16 in the 4000 block of South King Drive, and the other happened about 4 a.m. July 25 in the 5000 block of South Dorchester.
Police do not have a detailed description of the suspects.
