Shaileshkumar Hareshbhai Prajapati will go on trial for smuggling at the Ho Chi Minh City People's Court on July 30.

Prosecutors indicted three others alongside him: Nguyen Thi Linh, 54, for smuggling and offering bribes; Ly Thi Ngoc Bich, 47, for fraud; and Bich's older sister, Ly Thi Ngoc Nga, 49, for brokering bribery.

The operation traces to Shah Hemantkumar Sureshkumar, an Indian businessman known as Sunny who runs a firm called Nsh & Co. and directed Prajapati, his employee, to bring the diamonds in.

Shah's case has been separated from the trial because authorities have not yet received the results of a mutual legal assistance request to confirm his identity and background.

Shah traveled to Vietnam in early 2023 and agreed with Linh to move diamonds from India for illegal sale. From August 2023 he had Prajapati carry the stones straight to Ho Chi Minh City without declaring them.
