A row has broken out between the world’s richest person, Elon Musk, and a 19-year-old student and aviation enthusiast from Florida.

Jack Sweeney created the Twitter bot @ElonJet, which tracks Musk’s Gulfstream private jet and posts real-time updates of its location.

Musk, the co-founder and chief executive of Telsa and SpaceX, discovered the Twitter account and pleaded with Sweeney to delete it. “Can you take this down? It is a security risk,” Musk, who has amassed an estimated $220bn fortune, wrote in a direct message to the teenager. “I don’t love the idea of being shot by a nutcase.”

After a series of messages, which Sweeney has made public, Musk offered Sweeney a deal: “How about $5k for this account and generally helping make it harder for crazy people to track me?”

Sweeney attempted to negotiate. “Any chance to up that to $50K? It would be great support in college and would possibly allow me to get a car, maybe even a [Tesla] Model 3.”
