Police in Chicago's south suburbs apprehended two of five men who might have been armed Monday morning, and were searching for the remaining three.

Matteson police said early Monday morning, they received a 911 call about several people acting suspiciously in a residential neighborhood along Central Avenue and Vollmer Road. The people in question were reportedly armed with guns, police said.

Officers saturated the area and found the subjects driving out of Matteson in multiple cars, police said.

Matteson officers tried to pull over the cars, but they did not stop, police said. The cars were found abandoned shortly afterward, and video from CBS Skywatch indicated that at least one of them crashed.

Two suspects were in custody as of the 8 a.m. hour, Matteson police said. A search was still under way for any other suspects at large.

Tinley Park police, who were assisting, said earlier that there were a total of five subjects at large initially, which would mean three still on the loose as of the 8 a.m. hour.

The Will County Sheriff's office issued a shelter-in-place order for the area of Harlem Avenue and Vollmer Road while police searched for the armed men. Everyone in that area of Frankfort Square was asked to remain in their homes with their doors locked.

Will County Sheriff's office public information officer Kevin Hedemark said the area where the shelter-in-place was issued is very busy — with the Credit Union 1 Amphitheatre, a large Amazon fulfillment center, and an elementary school all located nearby.

A search perimeter was set up about three miles in each direction. Illinois State Police, Will County Sheriff's police, and Mokena police were also assisting.

Search dogs and drones were dispatched. Hedemark said all the police agencies involved were combing the area to ensure it was clear.

The shelter-in-place order was lifted later Monday morning. But while there was no longer a shelter-in-place order in effect by 10:45 a.m., Matteson police advised everyone to remain vigilant and to call 911 right away upon seeing anything suspicious.

Anyone with information relevant to the investigation is asked to call the Matteson police non-emergency line at 08-503-3130 or submit tips through the Matteson village website via Tip411.
