CAIRO (Reuters) - The chairman of Egyptian Traders Co said on Wednesday he had been issued with an arrest order in a row over a Russian wheat shipment that was rejected by Egypt and ordered re-exported. "An arrest order has been issued until the re-export LC (letter of credit) is cashed," Chairman Ashraf El Attal wrote in a brief e-mail sent by Blackberry to Reuters, adding that he would not be able to make further comment from now on. Egypt suspended grain contracts with Egyptian Traders, a private firm, on June 7 after the prosecutor ordered a Russian wheat cargo re-exported in a row over quality and the authenticity of an import document. Egypt told the firm to repay $9.6 million to Egypt's state grain buyer. |
