Clyde police are investigating Clyde-Green Springs schools superintendent Todd Helms, police Chief Bruce Gower confirmed Monday.
Gower declined to comment about what detectives are investigating, but said his office is working with the state auditor.
Gower said it could be several weeks before the investigation is completed.
Helms has been superintendent at Clyde-Green Springs since 2001.
"I don't want to comment until I find out more," Helms said Monday afternoon.
School board president Tom Conley said the board planned to meet in executive session Monday night to discuss the matter. He declined to comment until after the meeting.
Representatives of the state auditor's office did not return calls Monday afternoon.
Helms is a 1986 graduate of The University of Toledo and a 1997 graduate of The University of Findlay.
Before taking the superintendent position, Helms was the principal of Clyde High School. He also was a social studies teacher at his alma mater, Fostoria High School, and an assistant principal at Van Buren High School.
Clyde-Green Springs Schools have about 2,300 students in kindergarten through 12th grade.
