Giulio Regeni goes missing on the way to a friend’s birthday party, in a bar near Tahrir Square.

Regeni’s body is found by the side of the Alexandria Highway.

Egyptian investigators claim Regeni was killed in a road accident.

Egyptian state media reports that the police had found a gang responsible for the murder.

The University of Cambridge issues a statement saying it is “fully committed” to finding the truth, after criticism from an Italian minister.

Then-Italian Prime Minister Matteo Renzi attacks Cambridge for alleged “inexplicable” cooperation with the investigation.

The Egyptian National Security Agency admits that Regeni had been under surveillance prior to his death.

A lawyer representing Regeni’s family, Ibrahim Metwaly, is arrested by Egyptian police while en-route to Geneva to address a UN conference on disappeared peoples in Egypt.

Italian daily newspaper La Repubblica publishes a piece accusing Cambridge University of not cooperating with the investigation into the murder.

Regeni’s Cambridge supervisor, Maha Abdelrahman, has her computer and mobile phone seized.

Cambridge vice-chancellor Stephen Toope issues a statement in defence of Abdelrahman, saying the accusations in the Italian press were “damaging and potentially dangerous”.

Italian prosecutors confirm, as a result of their investigations, that Regeni was killed as a result of his research into independent trade unions.
