Tesla founder Elon Musk was hit by a lawsuit Monday, reports BBC, by the British cave diver who he repeatedly called a child abuser. The diver, Vernon Unsworth, helped rescue the young Thai soccer players who were trapped in a flooded cave in July. He is suing Musk for defamation, seeking financial compensation and an injunction to keep Musk from repeating the claims. Musk called Unsworth a "pedo" on Twitter after the diver criticized Musk for creating an unnecessary mini submarine to aid in the rescue.
