UNITED STATES: California prosecutors charged a man on Monday with raping, assaulting and robbing four young women while working as an Uber driver.

In the latest case involving the controversial US ride-hailing app, Alfonso Alarcon-Nunez picked up and raped the women while they were drunk in December and January, San Luis Obispo County District Attorney Dan Dow said.

He had worked for Uber since September, collecting his fare payments through the smartphone app Venmo to disguise his identity and his Uber records.
