COLBY, WI (WSAU) -  A staff member of the Colby school district is under investigation for possible inappropriate contact with a teenager. 

The Colby School District confirms a staff member has been accused of inappropriate conduct. That staff member has been on paid administrative leave for nine days. Marshfield Police investigators say the matter involves an offense which occurred outside of Wisconsin with a 17-year-old.

Colby Superintendent Steve Kolden says the district is also conducting its own investigation.

There was allegedly a different incident involving the same staff member and an 18-year-old male three years ago, but that case is not under investigation.
