CHICAGO (CBS) — Evanston police said Wednesday afternoon they have two persons of interest in custody after they were searching for occupants of a silver Jeep that was seen fleeing an area where shots were fired.

Police said they are not looking for additional offenders and that police presence will decrease.

Shortly after 3:30 p.m., the Evanston Police Department tweeted that they were in the area of Sherman and Lincoln looking for occupants who fled in the Jeep. The vehicle crashed at Sherman and Lincoln.

Police said the original incident occurred in the 2100 block of Darrow Avenue and that it did not involve nearby Northwestern University.
