Italian cartoonist, comic journalist and activist Gianluca Costantini has drawn a picture of Ali Rıza Arslan with the remains of his son Hakan in a bag. According to the artist, the picture appeared on a house wall in Istanbul.

Hakan Arslan died in 2016 during the siege of the old town of Sur in Amed (tr. Diyarbakir). His friends buried him next to a church, where his bones were found in 2021. Despite DNA matching, it took almost another year for the state to release the body. The Diyarbakır Chief Prosecutor's Office handed Ali Rıza Arslan his son's mortal remains in a bag on Monday. That same evening, the burial could finally take place in a cemetery in his home village in Erzurum province.

Gianluca Costantini published his drawing on his website Channeldraw, stating: "A court in Diyarbakır (Amed) in southeastern Turkey has summarily handed over the remains of Hakan Arslan, a young man killed when the Turkish government used the military against towns in the majority Kurdish southeast in 2015, to his relatives." On his social media accounts, Costantini shared the photo of the mural with the description "Hakan Arslan and his father on the streets of Istanbul".

In 2016, Gianluca Costantini was accused of terrorism by the Turkish government because of his drawings.
