The carjacking happened Feb. 6 on Essex Avenue, police say.
Charges were filed against a 20-year-old man accused of carjacking a woman at gunpoint earlier in February in the South Shore neighborhood.
Tyrone Cook allegedly confronted the woman Feb. 6 in the 7600 block of South Essex Avenue, according to Chicago police.
He allegedly took her belongings and vehicle at gunpoint.
Cook was arrested Wednesday and charged with a felony count each of vehicular highjacking with a firearm, armed robbery and aggravated unlawful restraint.
He was expected to appear in court Thursday.
In January, CPD Supt. David Brown outlined a plan to address the rise in carjackings, which have more than doubled in the past year.
