SEOUL, South Korea — The South Korean police raided the offices of Google Korea on Tuesday as part of an investigation into whether the company had illegally collected and stored personal wireless data.

The search company is already facing lawsuits and investigations in several countries in connection with private wireless data collected for its Street View service. Street View, which was started in 2006, allows users to view panoramic street scenes on Google Maps and take virtual walks through cities.

From late last year until May, Google Korea dispatched cars topped with cameras to cruise around the country to photograph neighborhoods before the planned introduction of Street View.

The police suspect that those cars might have illegally captured and stored personal data from wireless networks while they were mapping streets, a statement by the Cyber Terror Response Center of the Korean National Police Agency said.
