Feb.19 (GMM) Alleged Ferrari spy Nigel Stepney on Monday was questioned for three hours by Italian prosecutors.

Michael Schumacher's sacked former chief mechanic, accused of attempted sabotage and passing reams of secret information to rivals McLaren, was "cooperative and thorough", Modena magistrate Giuseppe Tibis is cited as relaying by ANSA.

The Italian news agency also quotes Stepney as saying he was "very calm" at the questioning, but his lawyer Sonia Bartolini told reporters that she thought other people have not been investigated enough.

McLaren officials including Ron Dennis and Martin Whitmarsh were originally slated to also be interrogated by Tibis on Monday, but their presence was called off.

The six McLaren chiefs, however, as well as suspended McLaren designer Mike Coughlan, remain under investigation, and are likely to be questioned in Italy in the coming weeks, ANSA added.
