A 15-year-old Utah boy has become TikTok famous after barricading with his sister inside a room at their mother’s house in order to avoid a judge’s order to reunite with their allegedly abusive father, according to a report.

Ty Larson has been using the video-sharing app for the last month to raise awareness about his and 12-year-old Brynlee’s ordeal after a state judge ruled the sibling need to be returned to their dad’s custody, according to a ProPublica report. Some of his videos, livestreamed from inside the bedroom, have hit more than 380,000 views.
