Anosh Ahmed is back in the U.S. and was in court Friday to face charges tied to a fraud scheme. He is now also being indicted in a COVID-19 test fraud scheme worth tens of millions of dollars.
Ahmed allegedly used patient data linked to COVID testing to seek money from the federal government.
He was first arrested in Serbia in January.
Ahmed is due in court on the second indictment on Monday.
A Chicago lab owner pleaded guilty earlier this month to conspiring with the former Loretto Hospital executive in the COVID-19 testing scheme.
In a change of plea, Mohamed Sirajudeen admitted to working with Ahmed to defraud the government of tens of millions of dollars.
Charges against two other co-defendants were dropped over allegations of misconduct by the U.S. Attorney's Office.
