DES MOINES, Iowa (AP) — Authorities say law enforcement officers descended on the Des Moines International Airport for what turned out to be a false alarm about a shooting. The officers headed to the airport around 8 p.m. Sunday. Des Moines television station KCCI reports that the call that spurred the quick response was made by a woman with mental health issues. Police say she reported shots being fired at a van.

The officers found no evidence of a shooting. The woman was taken to a hospital.
