A Penn State student faces a number of charges after he was seen allegedly committing a lewd sexual act on campus.

It happened in Penn State’s Boucke building, a few minutes before 11 p.m., on July 8. A Penn State employee was checking a room for trash when she found the student masturbating, with his pants down and shirt off.

The woman notified another worker who called Penn State police. Investigators identified the suspect as Ke Yang, 21, of 411 Waupelani Dr. Police say Yang was gone by the time officers arrived. He later agreed to meet with investigators after being contacted by phone.

According to police, Yang admitted to the charges, telling them he was addicted to pornography. Yang was arrested on Aug. 1 after police received word that he was planning to return to his native China.

Yang was arraigned before Magisterial District Judge Carmine W. Prestia, Jr. and sent to Centre County Correctional Facility. He was released on $10,000 straight bail. He’s due back in court on August 7. Yang is charged with indecent exposure, open lewdness and disorderly conduct.
