BERLIN (AP) — Swiss prosecutors say they have seized documents at a large Volkswagen dealer after a court ordered them to open a criminal investigation.

Federal prosecutors said Friday they have "secured evidence" at the AMAG Group, which is cooperating with the probe.

Some 2,000 criminal complaints were filed in Switzerland last year related to the Volkswagen emissions-rigging scandal.

At the time, Swiss prosecutors decided to forward all complaints to their counterparts in Germany, where the alleged wrongdoing had taken place.

Almost 600 Swiss plaintiffs took the issue to the country's top criminal court, which ordered prosecutors to open a probe in Switzerland as well.
