Elon Musk is being sued for calling one of the Thai cave rescuers a "pedo"
He made the remarks back in July.
Vernon Unsworth, a British diver who helped rescue the 12 young soccer players and their coach that were trapped in a Thailand cave, is suing Elon Musk for defamation following comments made by the entrepreneur earlier this year.
In the aftermath of the rescue mission in July, Unsworth was critical of Elon Musk's role in proceedings.
Musk built a submarine that he claimed was ready to go at any point and that it could be used to save the young boys.
The submarine wasn't used, and Unsworth himself said it "had no chance of working" and labelled it a "PR stunt".
Following this back-and-forth, Musk tweeted that he would post a video to prove that submarine would work, and ended it with: "Sorry pedo guy, you really did ask for it".
Musk pushed the issue, posting another tweet saying: "Bet ya a signed dollar it's true".
He has since deleted both of the tweets.
Unsworth has confirmed that he will be suing Elon Musk for his comments, and he has already filed a suit in California.
He is claiming that Musk's comments were defamatory.
According to the BBC, the lawsuit will seek $75,000 in compensation as well as 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".
