On 25 August 2009, the City of Rotterdam and the Port of Rotterdam Authority laid an information against former CEO W.K. Scholten and J.A.J. van den Nieuwenhuijzen. The suspicion is that Scholten, as an official, was bribed by Van den Nieuwenhuijzen.
On 25 January 2005, the City of Rotterdam and the Port of Rotterdam Authority laid an information in connection with suspected criminal acts. These related to Scholten’s unauthorised issue of loan guarantees in previous years to the RDM concern, owned by Van den Nieuwenhuijzen. This complaint led to an exhaustive criminal investigation by the Fiscal Information and Investigation Service and Economic Investigation Service (FIOD-ECD), headed by the National Public Prosecutor’s Office for Financial, Economic and Environmental Offences (FP), which focused on the two men.
