Authorities in Michigan say a high school teacher was arrested recently on suspicion of soliciting a sexual act from a juvenile student.

According to the New York Post, 41-year-old Charles Penn was an educator at Harper Woods High School in Southfield when he allegedly propositioned the 15-year-old girl, telling her she could improve her grades through the illicit act.

Police indicate the alleged incident took place earlier this year in the suburb of Detroit when the economics teacher and the victim were discussing her sagging scores.

When the teen asked what she could do to bring up her marks, the suspect allegedly suggested she perform an unspecified sex act on him.

Another student said she heard their conversation and contacted authorities, according to reports.

The Detroit News published a statement from Harper Woods police indicating that the agency “took immediate action and completed a thorough investigation.”

Police said the second student shared what she heard of the conversation and “corroborated what had occurred.”

Following his arrest, Penn was charged with accosting a child for immoral purposes on Thursday — about six months after the alleged crime.

Penn stepped down from his position at the high school after investigators launched a probe into the allegations.

If convicted, he could spend as much as four years behind bars.

As of the latest reports available, he remained locked up with bond set at $50,000 by District Court Judge Russell Ethridge.

He is set to appear for a preliminary examination early next month.
