Uber Technologies Inc. executive Anthony Levandowski will be fired in the next 20 days if he fails to fulfill an order by a U.S. District Court judge to hand over alleged stolen documents from Alphabet Inc.'s Waymo, Reuters reported May 31, citing a letter filed in court.

Uber's letter to Levandowski further adds that he failed to adhere to a written order to cooperate with the company's investigation. The Uber executive repeatedly invoked his Fifth Amendment rights when a U.S. district court requested him to produce the documents. Earlier in May, the ride-sharing company already warned Levandowski that he is bound to face possible termination for not complying to the court order.

Uber recently appointed Eric Meyhofer to replace Levandowski as head of the company's Advanced Technologies Group, the Reuters report said.
