Family, friends, colleagues and politicians gathered to pay their last respects to Michalis Zafeiropoulos who was assassinated in his office on Thursday evening.
The funeral service was held at the Hellinikon cemetery on Saturday afternoon.
Among those attending were President of Greece Prokopis Pavlopoulos and leader of New Democracy Kyriakos Mitsotakis.
Meanwhile, investigators have determined that the two men entered his office in central Athens at around 7 p.m. had an appointment with Zafeiropoulos.
According to the a law associate, the two men were aged between 30 and 40 and spoke Greek well but with a foreign accent that suggested they might be Albanian.
Initially the four men had a conversation in the lobby before the pair were led to Zafeiropoulos’s office. Once they were alone with him, one of them shot him in the chest at close range, killing him instantly.
As Zafeiropoulos’s office has no surveillance cameras, police are focusing on footage from the cameras of shops in the area in their bid to identify the killers.
The police investigation is focusing on recent cases undertaken by the 52-year-old criminal lawyer as investigators believe one of these may have provoked the perpetrators.
