It follows a US FCC report which found the engineer who created the code that grabbed the data told other Google employees about it. That report also found that data including medical listings and visits to pornographic sites was also taken by Google — not just limited information like Google had originally claimed. The ICO wants to know why it didn't get the same level of detail as the FCC did, and it wants to see the designs of the data slurping software. Google could face a £500,000 fine if the ICO decides the case is serious enough. The ICO's letter says it "seems likely that such information was deliberately captured during the Google Street View operations conducted in the UK.""
