A new generation of YouTube stars are staging prank terror attacks in public and angering a few people along the way, the Guardian reports.

The director apologized but said he was only mimicking American teens who get millions of hits by posting terror pranks on YouTube. British YouTuber Arya Mosallah, 17, recently saw his channel pulled after he posted a video of him approaching people in London, chatting with them, and throwing water in their faces. But he denied any connection to acid attacks, the BBC reports.
"I've never once mentioned anything about acid in the video," says Mosallah. "I could have said 'acid attack prank,' but never once have I ever said anything like that." He apologized to acid attack survivor Resham Khan, who called his video "childish and pathetic," but then started a second YouTube channel promising more pranks; it was promptly removed. In 2016, Australian police arrested the so-called Jalal Brothers for staging fake terror attacks and posting them on YouTube—including one in which an AK-47 was aimed at a child, the Huffington Post reported.
