California prosecutors have broadened their civil lawsuit against popular online ride-sharing service Uber, alleging that its background checks missed people convicted of murder and sex crimes, court records show.

The district attorneys of San Francisco and Los Angeles filed an amended complaint against Uber Technologies, Inc. on Tuesday, saying that “systemic failures in Uber's background check process” came to light after their initial December filing.

The new complaint says registered sex offenders, identity thieves, burglars, a kidnapper and a convicted murderer had all passed the firm's screening process and had been driving for the company until they were cited for providing illegal rides.

“I support technological innovation. Innovation, however, does not give companies a license to mislead consumers about issues affecting their safety,” San Francisco District Attorney George Gascon said in a statement on Wednesday.
