South Korea's antitrust regulator conducted an inspection of Google's local headquarters to investigate whether the firm is engaged in anticompetitive behavior over its Android operating system, Yonhap News Agency reported on Thursday.
Yonhap, citing unnamed sources, said the Korea Fair Trade Commission conducted the inspection last week and was probing whether Google forced smartphone makers using Android on its devices to not sell products using other operating systems.
Regulators began looking into the matter after the European Union brought charges against Google for anticompetitive behavior earlier this year.
Google and the Korea Fair Trade Commission declined to comment.
