In addition to reports that Gustav Brunner is implicated in the Toyota-Ferrari spy scandal, it has been confirmed that former F1 principal Ove Andersson has also been charged.
Prosecutors in Cologne, home of Toyota's F1 team, contend that former aerodynamics boss Rene Hilhorst is also involved, as well as ousted chief designer Brunner.
All three no longer work at Toyota.
The case, which dates back several years, hinges around ex-Ferrari workers who allegedly stole software from the Maranello team and used it to test aerodynamic data for the 2003 and 2004 Toyota single seaters.
“Toyota Motorsport has not been formally notified of the matter and does not have full knowledge of the specific issues,” a team spokeswoman explained.
It is expected that a German court will hear the charges some time this year, while the former Ferrari workers in question will be tried under Italian law.
The team spokeswoman added: “Toyota Motorsport would like to stress that the charges have not been brought against the company.”
Andersson led Toyota into F1 in 2002, and remained in charge in '03.
