Antivirus software entrepreneur John McAfee has been arrested in Spain following his indictment in the United States on tax evasion charges. The former Libertarian presidential candidate is accused of failing to file his taxes for four years despite millions in earnings from consulting work, speaking appearances, promoting cryptocurrencies, and selling the rights to his life story, according to the indictment filed in a U.S. District Court in Tennessee. He allegedly had the income paid into accounts registered under other names. If convicted, he could face five years in prison for each count of tax evasion. The Securities and Exchange Commission on Monday also filed a complaint accusing McAfee of falsely claiming to be an investor when he recommended cryptocurrency offerings without disclosing that he was being paid to promote them.
