The shooting took place late on Thursday evening after the victim cut off the electricity and water supply to a bakery premises he had leased to the attacker in the city in North Rhine-Westphalia.

He was shot with a pistol at close range at least once as he sat in a parked car, and died from his injuries while being taken to hospital in an ambulance. His brother was also in the vehicle but escaped harm after the weapon jammed.

The shooter, who leased the bakery but was late with his rent, then hailed a taxi and turned himself in to police, who recovered the weapon from the vehicle.

In a separate incident in Duisburg on Thursday, a 39-year-old man was shot in the stomach during an altercation. His condition was stable and a search was underway for the attacker, police said.
