HASTINGS, Neb. (AP) — Authorities say a 2-year-old and 8-year-old have been taken into state custody because they were found locked outside their south-central Nebraska home in the 91-degree heat.

Someone called police around 6:30 p.m. Sunday after spotting the children apparently trying to get into their Hastings home. The children reported that they’d been locked outside since before lunch.

The officers knocked on the residence doors, but no one answered. Police say the children seemed OK and didn’t need medical attention.

Police say the parents never did show up Sunday evening. It’s unclear whether they surfaced Monday. A police spokesman didn’t immediately return a call from The Associated Press.
