HOUSTON (CBSDFW/AP) – A man was arrested after he was accused of making a bomb threat against the University of Houston during a Zoom lecture.

Ibraheem Ahmed Al Bayati was set to make his initial court appearance Tuesday afternoon.

Al Bayati is accused by federal authorities of joining a university lecture on Zoom on Sept. 2 and interrupting it by saying “what does any of this have to do with the fact that UH is about to get bombed in a few days?”

Al Bayati, a 19-year-old U.S. citizen, told investigators the incident was a joke devised by him and a friend, according to a criminal complaint.
