Elon Musk appears to have doubled down on his claim that a British explorer who was instrumental in freeing a group of Thai boys trapped in a cave is a “pedo”.

The Tesla chairman was widely criticised last month for making the unfounded allegation against Vernon Unsworth, who was part of an international team that freed the young footballers and their adult coach from the Tham Luang cave complex in northern Thailand.

Unsworth had criticised a mini-submarine that Musk had delivered for the rescue as impractical and said he could “stick [it] where it hurts”.

Musk responded by calling Unsworth a “pedo guy”, later tweeting: “Bet ya a signed dollar it’s true.” He deleted both tweets soon after.

He has never presented any evidence for the allegation nor claimed to have any. He apologised for the remark last month after Unsworth threatened to sue, Tesla shares dived and the company’s investors issued an open letter demanding Musk apologise.

Musk was responding to another critic on Twitter on Tuesday night when he appeared to reaffirm the accusation. “You don’t think it’s strange [Unsworth] hasn’t sued me? He was offered free legal services,” he wrote.

“Did you investigate at all? I’m guessing answer is no. Why?” he wrote in subsequent tweets that are still online.

Musk has been under pressure from Telsa investors over his erratic behaviour on social media and record losses posted by the electric vehicle manufacturer.

He told the New York Times this month the past year had been “excruciating” and the “most difficult and painful of my career”, claiming he had been working up to 120 hours a week and neglecting his health and family.
