Venezuela’s once powerful oil minister, who resigned unexpectedly last year as prosecutors probed corruption and other wrongdoing at the highest levels of the state-run crude industry, has been arrested in connection with an alleged scheme that siphoned hundreds of millions of dollars from state coffers, the government announced Tuesday. The Ministry of Communications released images of Tareck El Aissami being handcuffed and walking down a hallway flanked by officers. Attorney General Tarek William Saab told reporters that El Aissami will make his first court appearance Tuesday on charges that include treason, money laundering and criminal association.
