Federal agents are investigating an assault in which a Muslim student in Missouri was struck and knocked down the stairs on “Punish a Muslim day.”

The incident on Kansas City’s Metropolitan Community College is being probed as a “possible hate crime,” the Kansas City Star reported.

FBI spokeswoman Bridget Patton said Wednesday the agency looked into all “logical leads” but has been unable to nab the culprit in the April 3 attack. A $10,000 reward is being offered for any information leading to an arrest.

The female student, who has not been identified, said she was leaving class last month when she heard a male voice make a derogatory statement.

She turned around and the person struck her in the face, which sent her tumbling down the stairwell, according to the newspaper.

The assault coincided with “Punish a Muslim day,” an anti-Islam campaign started in London that promotes violence against Muslims.

School officials released a statement saying the attack “goes directly against [Metropolitan Community College’s] values.”

“As a district, MCC will not tolerate discrimination or harassment against our students, employees, and community,” a spokesperson told the newspaper.
