Police have clashed with demonstrators during a protest in the Italian city of Bologna after a Moroccan-born man died pleading for help under police restraint.

Human rights campaigners and Italy’s opposition parties have demanded urgent answers over the death on Sunday of Abderrahim ⁠Fakir, 42, who had lived in Italy since he was five years old and ran a small removals and cleaning business.

A video shared widely on Italian media shows Fakir, who reportedly had heart issues and asthma, repeatedly calling out “aiuto, aiuto, basta” (Help, help, that’s enough) as two officers sit on him and ambulance workers look on.

After he stops moving, the police officers are seen binding his ankles together, only later checking his vital signs with the ambulance workers, the video shows. Prosecutors have opened an investigation and requested the officers’ body cam footage.

“You can’t die like this,” Fakir’s sister, Khadija, told the Corriere della Sera newspaper. “The police have to protect us. If someone is agitated, you have to calm them down … not kill them like a dog.”
