A concealed carry permit holder fatally shot a 22-year-old man who allegedly tried to carjack him in downtown Chicago early Friday morning, police told WLS-TV.

A 41-year-old man told police he was in his 2015 BMW when a 2019 Volkswagen rear ended him about 3:15 a.m. in the first block of Ida B. Wells Drive, WFLD-TV reported, which is in an area known as the "Loop" — Chicago's financial and governmental hub.

The BMW driver exited his car to inspect damage, and when he went back to retrieve his cellphone, WLS said the Volkswagen driver came at him with a handgun, demanded his keys, and pushed him into the vehicle.

Both men were inside the BMW when police said the 41-year-old — a licensed concealed carry holder — got his own handgun and shot the 22-year-old in the head, WLS reported.

The 22-year-old was taken to a hospital and later died, WLS said, adding that authorities haven't released his identity.

Police are questioning the 41-year-old man, WLS noted, adding in its video report that "police are calling it a homicide investigation; they have not labelled it a carjacking" but authorities are still looking at evidence and the BMW driver's statements.
