The interior ministry said in a statement that it has shared its findings with Italy, which was helping investigate the abduction and murder of the Cambridge University graduate whose mutilated body was found in Cairo in January. The ministry also released photographs of Regeni’s passport, university identification cards and a wallet. The manner of Regeni’s abduction and killing provoked accusations in Italy of Egyptian police involvement, something Cairo had strongly denied. Regeni, 28, had been researching labour movements in Egypt, a sensitive topic, and had written articles critical of the government under a pen name. The incident threatened relations between Egypt and Italy, a strong supporter of President Abdel Fattah al-Sisi whose security services have been accused of abusing dissidents. The ministry had announced earlier on Thursday that police had killed four members of a criminal gang that had kidnapped and robbed foreigners in Cairo in a shootout, without mentioning Regeni.
