Chicago police are warning residents in the McKinley Park neighborhood about a roving group of gang members in a car who have been attacking teenage boys.
Police said they recorded incidents during the month of March in the area bounded by 33rd Street to the north, 34th Street to the south, Seeley to the east and Leavitt to the west.
In each incident, police said, the offenders get out of a car, ask the victims if they are "Three Five," then beat the victims with pipes and knives before robbing them in some instances.
"Three Five" refers to a graffiti gang known to police in the area of 35th Street between Ashland and Damen on the near Southwest Side.
Police only provided a vague description of the offenders but said they have been seen in a black Honda Element with gray bumpers, a red Honda or a black sedan with a malfunctioning headlight and a possible partial Illinois license plate number N36.
Police urged residents who have any information to call the Bureau of Detectives at 312-747-8380.
