The UK’s Information Commissioner’s Office (ICO) has asked the search giant to provide more details about how their equipment attached to the cars collected personally identifiable information.

Google was asked to provide details on the type of data captured; timing of Google managers knowing the issue; and on how the search engine is managing the news, reports BBC.

The regulator also asked Google why it had not represented the full range of gathered data in a sample as it had done in 2010.

The ICO noted that the resulting captured data had included passwords, Web addresses, emails, and other sensitive data, such as online dating, transmitted over unsecured wireless networks.

"It therefore seems likely such information was deliberately captured during the Google Street View operations conducted in the UK," the data regulator added.

The current re-examination was prompted due to a separate investigation by the Federal Communications Commission into the gathering of data by Street View cars in the US, according to ICO.

A probe into the issue was previously dropped by the ICO based on the Google’s statement that they had mistakenly collected the limited data.
