- The School District of Rhinelander is working with the Oneida County Sheriff's Department to investigate thefts at the high school.
Cash has been stolen out of the lockers in the locker rooms.
The sheriff's department says it's been happening throughout the school year.
But it isn't a completely new problem.
"Thefts from the locker room at the high school have been an ongoing problem for years. When the high school remodeled, they bought different lockers," said Oneida County Sheriff's Department, Lieutenant, Lloyd Gauthier.
"The lockers that were there prior, they were susceptible to be broken into. The newer lockers are very safe as long as the students use a pad lock that's given to them."
The department is hoping to prevent more thefts.
Deputies are telling students not to take everything with them to class.
"Do they really need to take a large amount of cash, jewelry or cell phones; things of that nature maybe could be left in the main locker where it's secured," said Gauthier.
"Think about where they're going to be all throughout the day and what they really need instead of taking everything with them. Maybe forgetting to secure those things and then they may come up missing."
The department isn't saying what was stolen because they're still investigating.
