Turkish authorities on Wednesday detained 22 suspected members of the group in the southern city of Antalya after receiving a tip-off they were planning further attacks, the Dogan news agency reported. Meanwhile hundreds of lawyers, prosecutors and staff stood in respect on every floor of the giant Istanbul Caglayan Palace of Justice where Kiraz worked and the hostage drama unfolded. 'We will not forget you, our martyr,' read a gigantic banner, as a huge Turkish flag was hung from the top floor. The courthouse is to be renamed after Kiraz. Justice Minister Kenan Ipek said the two members of the DHKP-C who took him hostage had 'held a gun to the nation'. 'We don't see this as an attack on our deceased prosecutor, but on the whole justice system,' he said at a ceremony for Mr Kiraz.

Defiant: Mourners at the funeral of Kiraz hold a picture of the prosecutor high in tribute to the lawyer . Mr Kiraz, a father of two married to a judge who also worked at the courthouse, was targeted for his part in an investigation into the death of Berkin Elvan. The 15-year-old was severely wounded after being hit on the head by a tear-gas canister fired by a police officer during anti-government protests in Istanbul in June 2013. After spending 269 days in a coma, Elvan eventually died on March 11 last year. His death, and the subsequent investigation, have since become a rallying point for the country's far-left. Police chief Selami Altınok said officers stormed the building on Tuesday after hearing gunshots, and killed two of the gunmen. 'We carried out the negotiation for six hours. But our security forces launched the operation after gunshots were heard while terrorists were speaking on the phone during the negotiation,' he said. Critical: Prosecutor Mehmet Selim Kiraz was taken to hospital with gunshot wounds but died of his injuries . Shattered: The broken window of the room where prosecutor Mehmet Selim Kiraz was held hostage and shot . The emergency began at 2.36pm local time (12.36 GMT) when members of the Revolutionary People's Liberation Party-Front stormed into the office of Mr Kiraz. Images of a masked militant holding a gun to Mr Kiraz's head were then posted on the group's Facebook page, along with a demand for police to confess on live TV within the hour. Armed police rushed to the scene and were shown escorting court officials out of the building, but there was no sign of Mr Kiraz before the deadline arrived and live TV feeds were cut. Shots were then heard from inside the building, according to the Dogan news agency. In a statement published by Turkish media, the hostage taking was claimed by the Marxist Revolutionary People's Liberation Party-Front, which has been behind a string of recent attacks. The group published pictures showing one of the militants - his face concealed by a scarf with the group's red and yellow insignia - holding a gun to Kiraz's head.

Over: Istanbul Security Chief Selami Altinok, centre-right, and Deputy Chief Prosecutor Orhan Kapici speak to the media outside the main courthouse in Istanbul at the end of the siege . They had also plastered their flags and posters on the walls of his office. Turkish media said that the group had given a deadline of 3:36 pm (13.36 BST) for the prosecutor to identify the police officers who they say were behind the killing of Elvan or he would be shot. In a brief video message on a widely-followed Twitter account describing itself as that of Elvan's family, his father appeared to call on the group not to harm the prosecutor. 'We want justice. We don't want anyone to shed even a drop of blood. We don't want other mothers to cry,' Sami Elvan said. Prime Minister Ahmet Davutoglu met with the current and former interior and justice ministers at the ruling AK Party headquarters in Ankara to discuss the hostage taking, officials in his office said. Gunshots: According to the Dogan news agency, gunshots were heard from inside the building after the militant group's deadline passed . Demands: The group were demanding that Mr Kiraz name the policemen implicated in Mr Elvan's death, which has become a rallying point for the country's far-left . The DHKP-C said on its website it wanted the police officer it blames for Elvan's death to 'confess' on television, the officers involved to be tried in 'people's courts', and charges against those who attended protests for Elvan to be dropped. The DHKP-C blames the ruling AK Party for the killing of teenager Elvan. He was aged 15 at the time of his death, which was followed by mass nationwide protests that were also largely put down by the police. Elvan has since become an icon for the Turkish far-left and his supporters accuse the authorities of covering up the circumstances and perpetrators of his death. The United States, European Union and Turkey list the DHKP-C as a terrorist organisation. It was behind a suicide bombing at the U.S. Embassy in 2013. In 2001, two policemen and an Australian tourist died in a DHKP-C attack in central Istanbul. Innocent: Berkin was on his way to buy bread during anti-government street protests when he was struck in the head by a high-velocity gas canister . Strength of feeling: Elvan has since become an icon for the Turkish far-left and his supporters accuse the authorities of covering up the circumstances and perpetrators of his death .
