Taylor Swift's lawyers are trying to put an end to public tracking of her private jet, claiming it's 'a life or death matter'.
Student Jack Sweeney uses public data to track take-offs and landings of celebrity planes and posts them to Twitter.
US Correspondent Mitch McCann told Mike Hosking that the 21-year-old's been issued a cease-and-desist to stop sharing Swift's plane location.
He says Sweeney has responded that he believes in public transparency and hasn't promised he'll stop.
Swift's team claims the data gives her numerous stalkers "a roadmap to carry out their plans".
