The 1966-born Katsikas had been missing for several days before his body was discovered.

Police have arrested a home delivery courier who worked at a restaurant and knew the victim prior to the murder, according to a judicial source, who said that robbery is believed to have been the motive behind the killing.

The Greek foreign ministry has praised the late journalist as a conscientious professional, adding that the Greek consulate in Cairo is maintaining contact with the relevant Egyptian authorities to learn more details about the journalist's death.

The Hellenic Cultural Centre in Cairo has issued a statement mourning the loss of its vice president.

“The Hellenic Cultural Centre of Cairo says goodbye with sorrow to journalist Nikolaos Katsikas, a man who loved his work, Egyptian Greeks and Egypt,” the Centre said in a statement on Monday.

Katsikas had been working as a correspondent for the Athens Macedonia News Agency (AMNA) in Cairo since September of 2016. He also worked as a correspondent for Cypriot TV in Cairo.

An active member of the Greek community in Egypt, Katsikas founded Fos newspaper in Cairo and edited the monthly edition of Alexandrinos Tahydramos in Alexandria. Both publications are produced by the Greek community in Egypt.
