HARARE, Zimbabwe (AP) — Zimbabwe’s health minister on Saturday was charged with criminal abuse of duty as a public officer, accused of illegally awarding a multi-million-dollar contract for COVID-19 medical supplies to a shadowy company that sold the government $28 face masks and other materials at inflated prices.

The country’s anti-corruption agency arrested Obadiah Moyo on Friday and the government cancelled the contracts following public uproar.

The representative, Delish Nguwaya, and some top officials of the national drugs procurement agency are already facing criminal charges related to the scandal.

Nguwaya is accused of lying in saying the company was a drugs manufacturing company based in Switzerland, “whereas it was merely a consulting company with no experience in the manufacture of drug and medical products,” according to the charge sheet.

The scandal comes as health professionals including nurses and doctors in Zimbabwe are on strike demanding to be paid their salaries in U.S. dollars.
