Authorities say they're conducting an investigation into missing money at the Albion District Library.

The Battle Creek Enquirer reports the Calhoun County sheriff's department is assisting police in the southern Michigan city. Detective Sgt. Jason Kern says search warrants were executed Monday at the library and a home.

Kern says a request for charges is expected to go to the Calhoun County prosecutor's office after materials seized on Monday are reviewed.

There's no immediate word on the amount of the missing money.
