Moments before his arrest, Sin was using YouNow to chat with a man from Kuwait. In a video of their chat, beginning at 6 minutes and 52 seconds, a police car is seen driving up to Sin, and the Kuwaiti man begins imitating the sound of police sirens.

On Monday, Riyadh police said Sin was using the live-blogging service YouNow "abusively," according to Saudi newspaper Okaz. The police asked that people report similar situations in order to "preserve the values" of Saudi communities.

Many commentators on Sin's videos "demanded for him to be punished for his actions," Col. Fawaz Al-Mayman, a police spokesperson, told The Saudi Gazette.

“The two of them [Sin and Crockett] composed enticing videos which received thousands of followers and viewers from all over the world within a short period of time," Al-Mayman told the Gazette. "Most of the viewers were from the Arab world. Abu Sin...became famous and received negative attention."

Saudi lawyer Abdulrahman al-Lahem told Okazthat Sin could face one to three years in prison.
