(AP) — Wichita police arrested a 26-year-old woman after she left her three young children in the car alone on a day when the heat index reached 110 degrees.

A bystander called police Tuesday after noticing the children in the car for six to seven minutes with the windows rolled down. The mother left a 6-year-old girl and boys ages 3 and 1 while she went into a nearby business.

The children were placed with relatives.

The temperature reached 107 in Wichita Tuesday, the hottest day in the city so far this year.
