BELLEVILLE, Ill. (AP) — Police say the closing of two southwestern Illinois high schools was prompted by a teenager who took his mother’s handgun to possibly confront his girlfriend at one of the schools.

Belleville police said the 18-year-old man was arrested without any trouble Wednesday morning after officials had already closed Belleville East and Belleville West high schools for the day.
