A student recently discovered the books inside a bathroom at the university’s Student Union building. After snapping some pictures to document the apparent anti-Muslim act, he immediately reported it to campus security, which got police involved.

UT Dallas junior Mohammad Syed, a Muslim, said he didn’t believe the news until he saw photos published in the student newspaper.

“It’s definitely saddening and a little disturbing as well,” said Syed, who is the President of the UT Dallas Muslim Student Association. “It’s something that we do not expect to happen, especially at this campus.”

Syed said he’s always known UT Dallas as a diverse and inclusive place, which was the one of the things that drew him to pursue a degree in neuroscience there.
