Three former executives of car carrier company Wallenius Wilhemsen Logistics (WWL) have been indicted in the US on charges of price fixing.

The US Justice of Department (DoJ) said the indictments against Kai Kraass, Arild Iversen and Anders Boman were unsealed on Tuesday, but the men were indicted by a jury in November, 2016.

The move marks the latest phase in the US investigation into car carrier company collusion, following fines for four owners including WWL.
