Brazilian online publication O Popular reported on Wednesday that former Mirror Trading International (MTI) boss Johann Steynberg died on Monday of a massive heart attack.

Steynberg was under house arrest on a farm in Pirenópolis in the state of Goiás. He was arrested in December 2021, a year after fleeing South Africa, as the MTI crypto scam started to unravel.

O Popular also reports that Steynberg had escalating mental health issues, prompting his lawyer, Thales Jayme, to accompany him to a doctor on 15 April. He was diagnosed with severe anxiety. Just a week later, he reportedly died of a heart attack.
