At 2:17 a.m., a 911 caller reported a fight at the corner of West Addison Street and North Sheffield Avenue.
When authorities arrived, they discovered the fight was related to a strong arm robbery.
Six black males --- wearing white shirts, black bottoms, and carrying backpacks -- attacked a woman, knocked her to the ground, and stole her cell phone, said police.
Citing one eyewitness account, the violent thugs were last seen entering the CTA Red Line Addison station at 940 West Addison Street.
Despite being knocked to the ground, police said the victim wasn’t injured.
About an hour before this incident occurred, a thief knocked a man unconscious on the 1000 block of West Addison Street.
