There have been five carjackings in the last three days. Four of those carjackings took place in broad daylight Monday.

One happened just after 11 a.m. Monday near Irving Park Road in Uptown. The police alert includes the Uptown area.

The offenders rear-end the cars of the victims. When the victim stops and gets out of their car, to exchange information, the offenders enter the victim’s cars and drive off.

Police say it’s likely the same people are involved. Three young men between the ages of 18 and 25 are the suspected offenders.

This recent string of carjackings comes at a time when Chicago police say they are doubling down on their carjacking taskforce.
