Uber's general counsel Salle Yoo has warned Anthony Levandowski that if he doesn't return the files he's accused of stealing from Google's self-driving car unit and using them to develop similar technology at Uber, or open deny taking them, he could be fired
. Gizmodo reports: Uber's general counsel Salle Yoo warned Levandowski in a letter sent Monday and made public last night that, if he didn't return the stolen files or openly deny taking them, he could be fired. The letter is a result of a court order issued Monday, and Levandowski has until the end of the month to comply. "We understand that this letter requires you to turn over information wherever located, including but not limited to, your personal devices, and to waive any Fifth Amendment protection you may have," Yoo wrote. "While we have respected your personal liberties, it is our view that the Court's Order requires us to make these demands of you." Despite the allegations against him, Levandowski's job at Uber has been protected so far by his reputation as a rising star in the self-driving industry and his close friendship with CEO Travis Kalanick, who called Levandowski his brother from another mother. However, Yoo's letter hints that the tide at Uber may be turning against Levandowsk -- in addition to demanding he return Waymo's documents, Yoo also asks Levandowski to return any Uber files he may have and to only use Uber-issued devices for work, where his actions will be monitored. "If you have not fully complied with our prior request to return all Uber-owned documents in your possession, custody, or control, you must immediately return all such documents to us," Yoo wrote.
