Police are investigating the theft of cell phones, cash and other items from members of a high school marching band while they performed at the Children's Healthcare of Atlanta Christmas Parade in Atlanta.

Authorities say someone broke into the school bus, parked near Centennial Olympic Park downtown, and stole items belonging to members of the Central Carroll High School marching band.

Police said the bus was being watched by an attendant, but was left unattended for about 30 minutes. Police said iPhones, iPads, cellphones and cash were among items stolen.

School officials tells WSB-TV that the band plans to return next year to perform in the parade.
