A YouTube livestreamer was arrested Thursday after walking into a crowded room on the University of Washington campus and playing an audio clip stating that an explosive device had been "charged" and would soon detonate.

Authorities said the man, known as Arab Andy on YouTube, walked into the room filming on a phone, the University of Washington Police Department said in a statement.



"He asked for everyone's attention and a pre-recorded message emitted from a speaker on his jacket, announcing something to the effect of 'the C4 is charged' and a countdown began," the statement said.

Video of the incident, which has since been removed from Arab Andy's YouTube channel, shows people running out of the room after hearing the recording. Police said someone activated the fire alarm as they ran away.

"Dude you cannot get a better reaction than that," the man says on the video. "Holy shit."

The man, later identified as Jammal Harraz, was arrested shortly thereafter on suspicion of making a bomb threat. He is being held in King County jail on a $75,000 bail, according to online booking records.
