Ride-sharing firm Uber is facing a criminal investigation by the US government. The scrutiny has started because the firm is accused of using “secret” software that let it operate in regions where it was banned or restricted.

The software, called “greyball”, helped it identify officials seeking to stop the service running. A spokesman for Uber declined to comment on the investigation, reported the Reuters news agency.

It is claimed greyball was used in several areas, including Portland, Oregon, where the ride service was still seeking official approval to operate.
