WAUKESHA, Wis. (AP) A suspicious package found at a Wisconsin high school turned out not to be dangerous, and students are back in class.

The package caused concerns Wednesday morning and prompted a lockdown at Waukesha West High School. People were kept from leaving the school and entering it during the investigation.

Authorities in this city about 25 miles west of Milwaukee determined the package belonged to a student and didn't pose a threat.
