The Metropolitan Police will not be taking action against Google over the collection of data from Wi-Fi networks by its Street View service.
The Met had been considering action against Google since July after the company admitted to gathering the data, but said that, after consultation with the Information Commissioner's Office (ICO), it will not take the case any further.
"The Metropolitan Police has decided that it would not be appropriate to launch a criminal investigation," the force said in a statement sent to V3.co.uk.
"The Metropolitan Police has considered the allegations regarding alleged access to online activities broadcast over unprotected home and business Wi-Fi networks. Officers also liaised with the ICO."
V3.co.uk asked for more information on the Met's decision, but had not received a reply at the time of publication.
The news will come to a blow to privacy groups, some of which had lodged complaints with the Met over Google's actions under the Regulation of Investigatory Powers Act and the Wireless Telegraphy Act.
Jim Killock, executive director of the Open Rights Group, argued that the decision reflects the "weakness of data protection and interception law in the UK".
"This is illegal interception, exactly as was the case with Phorm. The authorities should be taking this very seriously. Action should be taken, and courts should decide what redress is needed," he said.
V3.co.uk also contacted Privacy International, but had received no response at the time of publication.
Google said that it had no comment to make on the announcement.
The decision mirrors that of the Federal Trade Commission in the US, which confirmed earlier this week that it will take no further action against Google.
The announcement also comes a day after MPs rounded on Google for the way it collected the data and for not initially revealing the full extent of the information. Google has said that it is " profoundly sorry" for the mistake.
