Google's cars captured data for the service between 2008 and 2010. During this time, it said that it unintentionally collected emails, photos and passwords. It also failed to then delete that data.
"In my estimation this is one of the most serious cases of violation of data protection regulations that have come to light so far," said Johannes Caspar, Hamburg Commissioner for Data Protection and Freedom of Information.
It was ruled that Google had captured and saved data without authorisation. A third party has now overseen that the data has been deleted.
The investigation has been going on for some time, but in November 2012 it was decided that Google would not undergo a criminal investigation as no violations had been found by that point.
Then Caspar reopened proceedings, leading to Google finding itself in more hot water. We say more as this isn't the first attack on Google over the Street View ordeal.
Google was previously fined a hefty amount by France, while the UK levied no fine, only requesting that all the data be deleted and no more be collected.
Google's fine almost hits the €150,000 limit, but Caspar requested that the maximum amount be increased in the future.
We've approached Google for comment, and will update if we hear more.
