US Treasury sanctions Gupta family, associate over South Africa graft

"The Gupta family leveraged its political connections to engage in widespread corruption and bribery, capture government contracts, and misappropriate state assets," Sigal Mandelker, Treasury Under Secretary for Terrorism and Financial Intelligence, said in a statement.

"We will continue to exclude from the US financial system those who profit from corruption."

The US Treasury's Office of Foreign Assets Control (OFAC) designated Ajay, Atul and Rajesh Gupta, and Salim Essa, a business associate of the family.

"As a result of today's actions, any property, or interest in property, of those designated within US jurisdiction is blocked," US Secretary of State Mike Pompeo said in a separate statement.

"The United States strongly supports ongoing efforts by the Government of South Africa, including its independent judiciary, judicial commissions of inquiry, and law enforcement agencies, to investigate and prosecute alleged instances of corruption," Pompeo added.

Ajay Gupta's lawyer Rudi Krause did not immediately respond to a telephone call and text message seeking comment.
