MILWAUKEE (AP) — A Milwaukee high school teacher is accused of repeatedly sending naked pictures of himself to a student.

Kenneth Chu is facing four charges in Milwaukee County Circuit Court, including three counts of exposing a child to harmful material.

Authorities say Chu sent the images to the student about 40 times and repeatedly told her he loved and wanted a real relationship with her.

Chu allegedly demanded that the student send photos of her body and threatened her with suspension if she didn’t comply with his requests.

Court documents say Chu created fake social media accounts to follow and chat with female graduates.

Chu faces a maximum combined penalty of 15 years in prison for the four counts. It wasn’t clear if he had a lawyer.
