Collinsville, IL (KSDK) - Illinois State Police are asking for information about a carjacking that happened just before noon on Thursday.
Police say the incident happened on Interstate 255 northbound, near Centreville, Illinois.
A 53-year-old female was driving a white 2004 Pontiac Bonneville with her 81-year-old mother in the passenger seat.
The Bonneville was traveling down the highway when a black 2001 Jeep crashed into the back.
Both vehicles pulled off to the side of the road, and when the 53-year-old woman got out of her car, two men got out of the Jeep, approached her, and took her car keys.
The second man physically removed the 81-year-old from the passenger seat, and the two suspects fled in the Pontiac, also stealing the 81-year-old's purse.
Two or three other suspects fled in the Jeep.
The suspects are described as four or five black males in their late teens or early 20s.
The 81-year-old was admitted to an area hospital for treatment to injuries she incurred during the incident.
The Jeep was previously reported stolen and was recovered along with the Bonneville.
Anyone with information on this incident should contact Special Agent Jamie Brunnworth at 618-346-3524.
