EL DORADO (AP) – Authorities say a broken axle caused a delivery truck to crash into a fence at a south-central Kansas correctional facility.

The El Dorado Correctional Facility was placed on lockdown for more than two hours afterward.

Kansas Department of Corrections spokesman Jeremy Barclay says the UPS tractor-trailer had just made a delivery when its axle broke shortly after 2 p.m. Monday. The truck went crashing into the fence.

Barkley says the fence wasn’t breached, and there was never a security risk.

Normal prison operations resumed before 5 p.m. after the truck was towed away and officials checked the fence.

The driver of the truck wasn’t injured.
