Yes, the TfL understand that at least 14,000 trips have been carried out fraudulently. A loophole in the app meant that unauthorised accounts, meant that photos of drivers could be uploaded to the app and other Uber driver accounts. The regulator TfL also found suspended and dismissed drivers who had been able to create Uber accounts and carry passengers on their trips. This was compromising passenger safety and security. Helen Chapman, Director of Licencing, Regulation and Charging at TfL, said" While we recognise Uber has made improvements, it is unacceptable that Uber has allowed passengers to get into minicabs with drivers who are potencially unlicenced and uninsured."
