This is the story of how one teenager abused thousands of children from behind a screen. Alexander McCartney used Snapchat, fake profiles and catfishing to target victims across the world. When a 12-year-old girl in Scotland reported what had happened to her, police began tracing the messages back to him. This video follows the start of the investigation, and the moment McCartney was arrested.
