(ANSA) - ROME, DEC 11 - Carabinieri police coordinated by the State attorney's office in Prato probing the deadly explosion of an Eni fuel depot at Calenzano have searched the facility near Florence as well as the Sergen company in Potenza tasked with maintenance work, according to media reports on Tuesday.
    Two of the five victims of the blast, Gerardo Pepe and Franco Cirelli who died with three tanker truck drivers at the facility on Monday, worked for Sergen. The State attorney's office in Prato, which has jurisdiction over the area of Calenzano, is reportedly looking into charges of manslaughter, disaster and "removal of culpable omission of safeguards against injuries on the job". Nobody has been officially placed under investigation yet, the reports said.
    According to Rome daily La Repubblica, the search warrant issued by prosecutors stated that Sergen was carrying out maintenance work near the fuel loading area, which has 10 platforms, where the blast occurred.
    The same newspaper also reported that, two months ago, tanker truck driver Vincenzo Martinelli, who died in the explosion together with colleagues Carmelo Corso and Davide Baronti, had denounced "constant anomalies" on the job in a letter to his company BT transport, responding to disciplinary measures against him opened by the firm after he refused to complete a trip.
