Bankrupt technical services company Imtech for years did business with companies in Iran, Syria and Sudan and at least four deliveries to Iranian firms are under US investigation, the Telegraaf says on Tuesday.

The paper says a former Imtech spokesman has confirmed the findings of an unpublished Imtech report on the sale of military equipment. The claims focus on the sale of radar and navigation systems made by Holland Signal, which Imtech took over in 2006.

The Telegraaf says Imtech’s own researchers have found 198 potential breaches of European and American export rules since the start of this year.

This means the new owners of the division – venture capital group Parcom and family firm Pon – could face multi-million euro fines, the paper says.
