The US Federal Communications Commission (FCC) has launched an investigation into Google's Street View service.
The investigation will determine whether or not the search giant broke privacy laws by collecting user data from unprotected Wi-Fi networks.
The FCC investigation comes days after the Federal Trade Commission dropped its on-going investigation into Street View maps service.
Michele Ellison, chief of the FCC’s enforcement bureau, said in a statement: “Last month, Google disclosed that its Street View cars collected passwords, e-mails and other personal information wirelessly from unsuspecting people across the country.”
“In light of their public disclosure, we can now confirm that the Enforcement Bureau is looking into whether these actions violate the Communications Act,” he added.
In the UK, the ICO, which had previously said that the data collected by Google was unidentifiable, has asked the company to revamp its privacy policies and has threatened it with an audit.
Conservative minister Rob Halfon has criticised the ICO for not sending "technical people" to investigate the Google Street View data breach scandal.
