Norway's economic crimes unit said Friday it had opened a fraud probe into German car manufacturer VW to see if cars sold in Norway had been equipped with pollution test cheating software.

"In light of the so-called Volkswagen affair in the US and Europe, where (the company) has admitted extensive cheating, Okokrim wants to investigate whether any crime has been committed in Norway and whether the fraud has had any effect on the cars imported to this country," the economic crimes unit said in a statement.
