A group of robbers have targeted at least seven people, mostly senior citizens, on Chicago's Northwest Side since February.
They are posing as city workers and work as a team to get inside the homes to steal jewelry, cash and other valuables.
Most of the robberies occurred in the afternoon or early evening hours.
The suspects were described as two to four males between the ages of 25 and 60 standing between 5-foot-6 and 6-foot-2.
Anyone with information is asked to call Area North detectives at 312-744-8263.
