An unidentified dean at Stevenson High School is under investigation after authorities said he sent inappropriate text messages to a female student.
Lincolnshire police were asked to look into the matter within the past week and found messages a parent might deem "inappropriate," Chief Peter Kinsey said Wednesday.
However, none of the messages appeared criminal, he said.
Copies of the text messages have been turned over to the Lake County state's attorney's office as a precaution, Kinsey said. No charges are anticipated.
School officials are actively investigating, Stevenson spokesman Jim Conrey said. He declined to discuss any details of the case because it is a personnel matter.
The dean remains employed, but Conrey would not say if he has been suspended or placed on leave.
The case arose a few months after Stevenson officials garnered media attention for following text messages between students as part of an investigation into illegal drug activity at the school.
One student was arrested in that case, but more faced campus disciplinary action.
