Gribkowsky was interrogated for eight hours yesterday, and his statements have reportedly piqued the prosecutors' interest in Ecclestone, who thus far has appeared before the courts solely as a witness.
The prosecutors have refrained from passing on any details concerning what is an on-going investigation, although they did confirm reports of Gribkowsky's interrogation.
According to the Financial Times (Deutschland), Gribkowsky was allowed to lie in an attempt to save his skin when he was the one on trial, but as a potential witness in this latest investigation involving Ecclestone he is obligated to tell the truth. Of course, an obligation is only as effective as the moral fibre of the one whose duty it is, so make of that what you will.
Gribkowsky retains the right to refuse to appear as a witness, but does not appear to have invoked it.
The FT report further states that - in German legal circles - the rumour doing the rounds is that the Munich prosecutors plan to arrest Ecclestone in the Hockenheim paddock. Apparently there was enough new information in Gribkowsky's comments to provide grounds for an arrest.
Ecclestone has long avowed that he would be at this weekend's German Grand Prix, but he is not due to arrive until Saturday. These latest reports make it increasingly unlikely that the F1 boss will be on Sunday's grid.
