SEOUL: South Korean prosecutors on Friday searched the local office of Volkswagen AG and sister firm Audi AG as part of a probe into an emissions case, a spokesman for the German carmakers’ local unit said, confirming media reports. Volkswagen and Audi face a flurry of legal complaints globally after Volkswagen admitted in September to falsifying US emissions tests on some of its diesel cars. Yonhap news agency said investigators from the Seoul Supreme Prosecutors’ Office raided the office and the house of an unidentified senior company official on Friday. They seized e-mails exchanged with headquarters and documents on emissions verification and vehicle certification, the report said.
