German retail giant Rewe is being investigated as part of a price-fixing investigation in Austria.

The Austrian competition authority, the Bundeswettbewerbsbehörde, confirmed today (1 March) that it had searched Rewe's offices amid claims of collusion with suppliers.

A statement from the BWB issued on Tuesday said only that a search had been made in the food retail sector amid suspicion of price fixing.

Officials at Rewe could not be reached for immediate comment. At the end of 2010, the most recent figures on the Rewe Austria website, the retailer had 2,475 stores in the country.
