According to police, the offenders are a group of two to four men between the ages of 18 and 25 traveling in a gray four-door vehicle. Victims told police one of the suspects has dreadlocks.
One robbery took place at 10:20 p.m. Friday near 23rd and Wabash. The others took place between 3 a.m. and 7 a.m. Saturday.
Police said the offenders typically approach victims on the street. In some cases, the victims were beaten before their property was stolen. In other incidents, one of the offenders showed a black semi-automatic handgun before demanding property.
CPD has asked that South Loop residents be on the lookout for the offenders. No suspects were in custody Sunday.
