The ABC's Chris Uhlmann reports:
"The email at the centre of the OzCar affair has been found and is a fake, the ABC understands.
This morning Australian Federal Police officers executed a search warrant at the house of Treasury official Godwin Grech, whose evidence to a Senate inquiry on Friday ignited the OzCar scandal.
The email was purported to show the Prime Minister's office making representations to the Treasury on behalf of car dealer John Grant, Kevin Rudd's friend and political donor.
AFP cars are at Mr Grech's house in southern Canberra and IT specialists are investigating the email, which is believed to have been sent from Treasury to his home account.
Police are now interviewing Mr Grech about the email."
