A 25-year-old Sun Prairie high school employee was fired after she was accused of inappropriate contact with a teen boy, officials said.

The Sun Prairie Police Department said Janet Kula was taken into custody Friday on a charge of sexual assault of a child by a school staff person. 

Police said Kula began a relationship with a 17-year-old Sun Prairie high school student in November that became inappropriate over the following month.

Police said the case has been sent to the Dane County District Attorney's Office.
