The Frankfurt am Main public prosecutor's office said Wednesday that investigators from Germany, Italy and Switzerland have searched ten commercial properties belonging to Fiat Chrysler Automobiles NV, IVECO SpA, Jeep and Alfa Romeo in connection with the ongoing diesel scandal.

According to a statement, the properties searched were in Baden-Wurttemberg, Germany, the Swiss canton of Thurgau and the Italian region of Piedmont.

The search aims to obtain evidence regarding a shutdown device which allowed car makers to cheat CO2 emissions requirements.
