The Saudi boy, known online as Abu Sin, faces years behind bars after he was arrested for his behaviour in videos exchanged with Christina Crockett on popular live-streaming site YouNow.
Riyadh spokesman Colonel Fawaz Al-Mayman said the 19-year-old was arrested for his “unethical behaviour”.
Al-Mayman said: “His videos received many comments and many of the commenters of the general public demanded for him to be punished for his actions.”
The pair struck up an unlikely friendship when they met by chance via the video chat site YouNow.
Videos of the pair communicating with one another and dancing to each other were then uploaded onto YouTube where they gained thousands of followers.
The language barrier between the pair was apparent but interaction between them was a hit with viewers.
Ms Crockett, 21, invited Abu Sin to one of her split screen chats during one of her broadcasts – known as “guesting”.
She said: “I guested this kid – I don’t know what he’s saying because I don’t speak Arabic, [but] everyone thought he was really funny, and everyone liked him, and I guess this video went viral.
“He didn’t speak much English, so I was trying to get him to understand what I was saying most of the time; it wasn’t that good communication.
“He was dancing and being funny, we would both dance on there because we can’t communicate with words. It was pretty funny.”
Ms Crockett, who has a boyfriend, described the situation as “totally crazy and unfair” but that she did not feel responsible as she had “no control over it”.
Abu Sin was arrested by Saudi authorities during a live stream while in a car with two of his friends.
During the stream, his friends explain Abu Sin was arrested before the clip suddenly cuts out.
If found guilty, Abu Sin could face up to three years in prison.
The Saudi youngster has since been released on bail.
