Egypt's top prosecutor Hamada El-Sawy has ordered the formation of a new investigative team to solve the murder of Italian student Giulio Regeni, who was tortured and killed in Cairo in 2016.

The new team will "take all the necessary investigative measures to uncover the truth with complete neutrality and independence," according to a statement issued by the prosecutor-general on Wednesday.

The decision comes after two days of meetings between Egyptian prosecutors and their Italian counterparts, which concluded on Wednesday.

Regeni, a 28-year-old student who was doing postgraduate research on the Egyptian labour movement, disappeared on 25 January 2016, the fifth anniversary of the 2011 revolution. He was found dead 10 days later in a ditch on the outskirts of Cairo. Egyptian investigators said his body bore signs of torture.

El-Sawy stressed that the prosecution authorities of both countries are cooperating to uncover the truth behind the killing with "complete objectivity and transparency, away from false information reported by the media about the case."

Egyptian and Italian authorities have been holding regular meetings in Cairo and Rome to discuss the investigation into the murder.

Egyptian officials have repeatedly dismissed reports that security officials were involved in Regeni’s killing.
