A man and a woman were taken into custody Wednesday after being in possession of a car stolen in St. Clair County Tuesday night, and police are still looking for at least one more carjacking suspect.

The St. Clair County Sheriff’s Office is still investigating after the woman was carjacked at gunpoint Tuesday night with her children in the back seat of the car.

Police responded to the 2600 block of Eastview Drive in Belleville around 11:30 p.m. where a 23-year-old woman was carjacked.

The two suspects let the woman take her 3-year-old daughter and 6-month-old son out of the car before they took it. The woman's car is a silver 2009 Pontiac G8.

On Wednesday, police in St. Clair County located the car and took the man and woman into custody after a chase that crossed state lines multiple times. Police said they do not know if the man arrested was involved in the carjacking and they are still looking for at least one more carjacking suspect.

The suspect’s vehicle is described as a gray or black newer model Jeep Cherokee with Missouri license plates.

Swansea police also reported a similar incident 10 minutes before the Belleville carjacking, at a gas station on the 1600 block of North Belt West. Police released photos of the incident on Facebook. They are still working to determine if the cases are connected.

“We certainly want to stop any violent crime, and cooperation from the public is key to that happening. It was fortunate that no one was injured, but these are very serious crimes that we want to get resolved as soon as possible,” Captain Bruce Fleshren said in a press release

Investigators are working together to identify possible suspects in both incidents. Anyone with. information should contact the St. Clair County Sheriff’s Department of Swansea police.
