The homes of Porsche ex-chief Wendelin Wiedeking and his former finance chief Holger Haerter have been searched in connection with a probe into possible insider trading.
The German auto giant has had a stormy time of late
The company had said on Thursday that prosecutors with search warrants had searched the Porsche headquarters in Stuttgart, but now the city's prosecutor's office has confirmed that the men's private apartments were also raided. Both Wiedeking and Haerter resigned last month after the luxury automaker failed to acquire Volkswagen.
The men are now being examined by Germany's financial supervisory authority (BaFin) on suspicion of market manipulation
Wiedeking faces investigation into alleged insider trading
The German news magazine Der Spiegel's reported in the its issue to be published on Monday that the investigation is into attempts to stabilize the shares of VW and keep them from fluctuating amid a lengthy takeover attempt by Porsche. Porsche owned more than half of VW's shares at the time and such fluctuations could have led to massive losses for the company.
The failed takeover left Porsche mired in debt.
Porsche has denied the allegations of market manipulation and said it would cooperate and assist investigators.
Porsche and Volkswagen have now agreed on a plan to integrate the two carmakers by 2011, creating a new German automative giant.
