A senior interior ministry official said Monday night that the ministry has "no information" about the existence of reported video footage showing Guilio Regeni – the Italian found murdered in Cairo last month – involved in an altercation with an unknown person shortly before his disappearance.

"Any reports [in the case] not [officially] announced by the interior ministry are only rumours," Egypt's assistant interior minister for PR and media Abu Bakr Abdel-Kerim told the Enferad TV programme on Al-Assema channel.

On Monday morning, judicial sources said the Giza prosecutors, who are investigating the murder of the 28-year-old Regeni, ordered the reviewing of footage from a surveillance camera in the vicinity of the Italian consulate in downtown Cairo.

Sources told Ahram Online that the footage showed Regeni involved in a heated verbal argument with someone days before his disappearance on 25 January.  

The assistant interior minister said that the ministry is giving the case top priority and that there is constant coordination with Italian security representatives in Cairo, with Egypt providing Italy with the latest information.
