A math professor at Northern Virginia Community College has been charged by Prince William County Police with sexual assault after two separate students at the Manassas campus accused him of rape.

Youssef Taleb, 27, was charged with rape, object sexual penetration and two counts of sexual battery on May 5, after both alleged victims submitted arrest affidavits.

In the affidavits, one student told school police that Taleb had sexually assaulted her on May 3 after taking her into a conference room to help her with classwork and that he had also raped her on March 22. The other woman, who also made a report on May 5, alleged that Taleb sexually battered her earlier in the semester.

The accusers were not in the same class and were not acquainted with one another, police said.

Prince William County Police have searched Taleb’s Fairfax County home and taken clothing, a cellphone, documents and photos in hopes of finding evidence of a sex crime.

Taleb was hired last August to teach at the Manassas campus and was fired on May 12, one week after the accusations were reported to police. He is now being held in Prince William County jail.

The college said it has alerted students and staff about the incident and have new concerns about safety.

“It’s very shocking because I actually just had him this spring and he was very professional and very supportive in class, so it was very shocking to find out he’s involved in this,” NVCC student Jeannette Amya told the Washington NBC affiliate. “I would never guess to see it coming.”

Taleb’s attorney has not yet responded to the press.
