The public prosecutor’s office is looking into a possible case of corruption involving the sale of railway land to a property developer, the AD reports.

The case centres on one of two controversial deals struck by Dutch railway company NS in 2010 and 2014, the paper said.

The strips of land were sold by Dutch rail to property developers Railside and Bakkhe Vastgoed for almost nothing after track operator ProRail turned the deals down. However, ProRail was later forced to buy the land for millions of euros because it was needed for widening the tracks and building bridges.

The current investigation focuses on the sale of land to Bakkhe Vastgoed, which, the paper says, may have profited from inside information from a former shareholder in Railside. Railside bought the first package of land in 2010.

The NS has already conducted an internal investigation into insider dealing but found no basis for it, a spokesperson told the AD.

Meanwhile parliament wants more information about how millions of euros of public money were wasted on railway land in what current ProRail boss Pier Eringa called ‘a shambles’, the paper writes.
