Everyone loves a great YouTube prank video, but sometimes people take these public pranks way too far. “Arab Andy”, a popular YouTube pranker, found this out the hard way when he was arrested on May 31 for attempting one of his jokes.

According to authorities, the suspect was trying to pull off a distasteful prank that involved a bomb threat inside of a University of Washington classroom. The suspect began livestreaming himself as he burst into the class. He raised his cellphone into the air, and it played a disturbing message: “C4 has been successfully activated. Bomb detonation countdown successfully started.”

Terrified students can be seeing fleeing the room before a loud explosion is heard in the room. The explosion noises stemmed from the suspect’s cell phone. One student triggered the school’s fire alarm to raise awareness about the threat. The livestream continued as faculty and students were all evacuated from the area.

When police arrived on scene, they arrested the suspect. He is being charged with making a bomb threat, but authorities did discover there were no real or active bombs or devices in the room. Police determined there was no ongoing threat or danger to the school’s students. Fake bomb threats, even when joking around, are considered a class B felony in Washington state. The YouTuber could potentially be facing a $20,000 fine and 10 years in prison, but authorities have not yet determined whether they will be pressing charges after the incident. Although thousands of individuals viewed the prank live, YouTube has since decided to remove the content for violating its terms of service.
