McLaren have been informed of another investigation into alleged spying after Italian prosecutors visited the British team at the Monza circuit on Saturday night.
The team are already due in Paris on Thursday to face the World Motor Sport Council for a second time about the affair after the arbitrators claimed they had uncovered new evidence. McLaren were found guilty of fraudulent conduct after the first hearing but were not penalised due to a lack of evidence.
Italian prosecutors are still in proceedings against former Ferrari head of performance development Nigel Stepney, who is accused of sabotaging the team's cars at the Monaco grand prix.
The Italian authorities appear to be widening the investigation to include the alleged spying between Formula One's top two teams. (more)
