PARIS—Police have raided Volkswagen AG’s main office in France in connection with the probe into the company’s rigging of emissions tests, a company spokeswoman said Sunday.

The raids, which took place on Friday but weren’t reported before Sunday, targeted the German car maker’s France headquarters in Villers-Cotterêts and a second office near Paris. “We cooperated with full transparency,” the spokeswoman said. A spokeswoman for the Paris prosecutor’s office said computer hardware was seized in the raids.
