CHICAGO -- Police warn CTA commuters who take the Red Line to look out for thieves.
There have been three robberies this week.
During the robbery, three-to-four offenders approach the victims outside of a CTA Red Line Station or on the train.
One asks a question to distract the rider -- then the others punch the victim in the face multiple times and goes through their pockets or purse.
Two of the robberies happened just after 1 a.m. Friday; the first incident in the 100 block of West Adams -- then 20 minutes later again, in the 100 block of West Van Buren.
Another robbery was reported around 11:20 p.m. Wednesday in the 100 block of South State.
Anyone with information should contact Area Central Detectives. The advice from police: Be aware of your surroundings.
