MINNEAPOLIS (AP) -- A Wisconsin school district has put a staff member on leave after some students from Madison East High School found recording devices in their hotel rooms during a field trip to Minneapolis.

A Madison school district spokesman says the response was a cautionary measure that's standard during a police investigation.

School officials say they're working to support the affected students and families.

A Minneapolis police spokesman says no suspects are in custody.
