Officials in Spain, France and the Czech Republic announced plans on Thursday to investigate Google’s collection of data from wireless networks in their countries, raising the likelihood that the company could face sanctions in Europe. Five days after Google said it had inadvertently collected 600 gigabytes of data described as snippets of Web sites and e-mail messages from unsecured Wi-Fi networks around the world, privacy lawyers said Google was likely to face fines and suffer damage to its reputation. Data protection officials in Spain, the Czech Republic, France and Germany have started administrative inquiries into the company’s practices, which they said violated local privacy laws. Investigators at France’s National Commission on Informatics and Liberties said they had inspected Google’s Paris office on Wednesday as they began to gather evidence. In the United States, two members of Congress asked the Federal Trade Commission on Wednesday to begin a review of what Google had collected. In Hamburg, prosecutors opened their criminal investigation this week after receiving a complaint from Jens Ferner, a law student completing an apprenticeship at his father’s law firm in Alsdorf, Germany. During an interview, Mr. Ferner said German courts had taken a strict line with those convicted of using Wi-Fi networks without an owner’s knowledge. In Britain and Ireland, by contrast, regulators said they were not initiating investigations but had asked Google to destroy the data collected in their countries. Google said last weekend that it had destroyed data collected in Ireland, at the request of the local regulator.
