Uber allegedly used secret program to undermine rival Lyft

Program - dubbed 'Hell' - was reportedly run between 2014 and early 2016 in order to deprive cab competitor of drivers

A secret Uber program internally dubbed "Hell" allegedly spied on arch-rival Lyft to determine which drivers were working double shifts for both companies, letting the cab-hire app steer more work towards them in an attempt to deprive its competitor of workers.

The report of the "Hell" program continues a string of uncomfortable claims for the company, still dealing with the fall-out of a string of sexual harassment allegations at the beginning of the year, and now operating with a brand new head of public policy and communications following the departure of its previous PR chief, Rachel Whetstone, on Tuesday.
