A British cave diver is suing tech billionaire Elon Musk for defamation after his repeated claims the diver is a child abuser.
Vernon Unsworth helped with the rescue of 12 Thai teenagers from a flooded cave in July.
Mr Musk has made several accusations against Mr Unsworth without evidence, including that he was a “child rapist”.
The lawsuit seeks $75,000 in compensation and an injunction against Mr Musk to stop further allegations.
The filing also says Mr Unsworth is seeking “punitive damages” as well as the compensation, “to punish him for his wrongdoing and deter him from repeating such heinous conduct”.
It says Mr Musk sometimes used his Twitter account and emails to “publish to the world false and defamatory accusations” against the Briton.
His account had over 22.5 million followers during this time, the filing states.
The South African-born head of Tesla previously tweeted it was “strange he hasn’t sued me” when Mr Unsworth said he was considering legal action.
You don’t think it’s strange he hasn’t sued me? He was offered free legal services. And you call yourself @yoda …

Mr Unsworth filed the suit in California. A separate suit will follow in London, the filing says.
“Musk’s influence and wealth cannot convert his lies into truth or protect him from accountability for his wrongdoing in a court of law,” Mr Unsworth’s US attorney, L Lin Wood, said.
The pair first clashed over Mr Musk’s offer of a mini-submarine to help with the cave rescue.
The entrepreneur posted footage of the vehicle on Twitter and suggested it could be used to help save the trapped teens.

Mr Unsworth told CNN that the submarine was “just a PR stunt [that] had absolutely no chance of working” and said Mr Musk could “stick his submarine where it hurts”.
The Tesla founder responded with a series of tweets accusing Mr Unsworth of paedophilia.
Although he later deleted the tweets and offered an apology to the diver, Mr Musk reignited the row earlier this month.
An email to Buzzfeed reporter Ryan Mac included the claim the Briton was a “child rapist”, imploring the reporter to “find out what’s actually going on” and suggesting the diver took no part in the cave rescue.
The billionaire also said he hoped Mr Unsworth would sue him.
Mr Unsworth did not take part in the dives but had previously explored the cave complex extensively.
He knew about the raised ledge known as Pattaya Beach where the boys and their football coach could have sought shelter, travelled into the caves shortly after they went missing and called in the two expert British divers who eventually found the trapped group.
Several divers told Buzzfeed that he had worked continuously on the rescue. “He was pivotal to the entire operation,” said British diver Rick Stanton.
