Sep.8 (GMM) We can now reveal more details about the visit on Saturday of Italian police to the Monza paddock.

McLaren team boss Ron Dennis was served with an 'avviso di garanzia'; a formal warning that he is to be investigated by criminal prosecutors in the northern region of Modena.

The notice lists Dennis' alleged wrongdoings as frode sportive (sporting fraud), rivelazione di segreto industriale (industrial espionage), and another unknown offence, with relation to the so-called spy saga involving the British team's championship rival Ferrari.

The recipients of two other notices given out by the police at Monza on Saturday are believed to be Martin Whitmarsh (F1 CEO) and managing director Jonathan Neale.

It is understood that three more McLaren employees, including suspended chief designer Mike Coughlan, will receive their notices at McLaren's Woking headquarters shortly.

The final recipient is Ferrari's sacked Nigel Stepney.
