Italian investigators are continuing to question several senior figures from Formula 1 teams McLaren as part of the ongoing spy scandal.
Although world governing body, the FIA, concluded matters of a sporting nature in September, the legal process continues.
The FIA fined McLaren €66 million and stripped the team of all constructors' points for 2007 after they were found guilty of being in unauthorised possession of technical information belonging to rivals Ferrari.
That was after a 780-page Ferrari dossier was discovered at the home of chief designer Mike Coughlan.
Nigel Stepney, sacked as Ferrari's head of performance development and alleged to have passed the information on to Coughlan, was last week questioned on the matter by Modena prosecutor Giuseppe Tibis.
It is understood team principal Ron Dennis, F1 CEO Martin Whitmarsh, engineering director Paddy Lowe and senior employees Jonathan Neale and Rob Taylor have all been quizzed at their homes.
A statement released by McLaren read: "McLaren Racing has today continued its co-operation with enquiries instigated by the Modena Magistrate.
"The Surrey Police accompanied Italian investigators to the homes of a number of McLaren executives as part of their ongoing investigation.
"A similar process has been performed at the McLaren Technology Centre.
"The police are completely satisfied with the co-operation they have received.
"These actions are part of a normal judicial process in connection with the ongoing investigation, and are supported by McLaren Racing."
