(ANSA) - Potenza, April 20 - A detention review court in Potenza on Wednesday rejected appeals from five ENI workers under house arrest since March 31 in a probe into suspected graft and waste trafficking at Basilicata oil facilities. The workers are employed by ENI's Centro Oli treatment plant at Viggiano near Potenza. All appeals against a preliminary investigations judge's detention orders were rejected. In the probe, two government ministers have been questioned but are not under investigation: former industry minister Federica Guidi, who quit over an amendment favouring her oil-industry boyfriend, and Reform Minister Maria Elena Boschi, who signed the amendment in her other capacity as minister for relations with parliament.
