The unknown perpetrator or more of them damaged a statue in Sarajevo's central park, dedicated to a wartime tragedy, the police confirmed Thursday.

“An unknown person damaged the memorial and cut off the arm on the statue,” Sarajevo Canton police spokesperson Suvada Kuldija confirmed.

The statue symbolically called ‘Nermin, come here!’ portrays a father in the eastern town of Srebrenica, who calls his son to surrender to the Bosnian Serb forces and join him.

“One of the most disturbing scenes of the Srebrenica genocide against innocent Bosniak population is the scene of a father calling his son Nermin to surrender and telling him the Serb soldiers will supposedly do him no harm. Ramo (the father) and his son Nermin were found by exhumation teams in 2008, in a mass grave not far from Srebrenica,” reads the note on the memorial.

The police said the investigation into this case is underway.

On July 11, 1995, Bosnian Serb forces overran the eastern Bosnian enclave of Srebrenica and rounded up the town’s Muslim Bosniaks, separated men from women and little children and systematically executed some 8,000 men and boys.

The bodies of the victims were buried in a large number of mass graves. Forensic experts excavated them and identified the bones through DNA analysis before returning the bodies to the families for interment on July 11 at the Memorial Centre’s cemetery.

The International Criminal Tribunal (ICTY) for the Former Yugoslavia and the International Court of Justice later ruled that the massacre was an act of genocide.
