A group of robbers hit two businesses last month in the Grand Central district.
In both incidents, a group of two to three people walked in with a weapon, announced a robbery and stole cash, according to Chicago Police.
The robberies happened at 2:02 p.m. on Dec. 11 in the 4100 block of West Belmont and about 7:45 p.m. on Dec. 19 in the 1500 block of North Cicero, police said.
The suspects were described as three black males between 17 and 20 years old, two of which are 5-foot-5 to 5-foot-8 and the other about 6 feet tall, police said. All have slim builds.
Anyone with information was asked to call Area North detectives at (312) 744-8263.
