Google violated Britain's data protection laws when its Street View mapping service recorded data from private wireless networks, the country's information commissioner said Wednesday.
The American Internet search giant will escape any fines, however, so long as it pledges not to do it again.
Google drew international outrage after it emerged that its Street View cars, which take street-level photographs to illustrate the company's popular mapping service, had also been scooping up e-mails, Internet addresses and passwords from unencrypted wireless networks.
Scotland Yard recently said it would not launch a criminal inquiry into the beach, which the company has described as inadvertent.
Information Commissioner Christopher Graham was recently given the power to levy fines up to 500,000 pounds (about $800,000) for serious violations, but he said in a statement that the "most appropriate and proportionate regulatory action" would be to seek a written assurance from Google that the breach would not be repeated and conduct an audit of the company's data protection practices.
The company based in Mountainview, California said in a statement that it "was profoundly sorry" for the breach, adding that it had since worked to improve its internal controls.
"We did not want this data, have never used any of it on our products and services, and have sought to delete it as quickly as possible," the statement said.
