"Following a dispute between several individuals on the public highway, a man was the victim of a firearm," said a first police source.
The victim died on the spot and the suspect, who fled by car, "was arrested" shortly after the incident and taken into custody, she added.
A fight that escalated
The facts took place on Boulevard de Clichy, in the 18th arrondissement, north of Paris.
According to the first elements of the investigation, a fight opposed several people on the median when a motorist stopped his car to go to meet them, explained a second police source.
One of the participants in the brawl would have ordered him to "clear".
The driver then pulled out a gun and shot him in the head before getting back behind the wheel, according to the same source.
A suspect arrested and an investigation opened
The CCTV images enabled a crew from the anti-crime squad to locate the empty car of any occupant.
A device was set up near the vehicle until the suspect returned with suitcases in his hands.
At the sight of the police, the man took out his weapon again and a chase began on foot before he finally let himself be arrested without shooting.
He was placed in police custody and an investigation in flagrante delicto for murder was opened, entrusted to the 2nd district of the Parisian judicial police (2nd DPJ), according to the Paris prosecutor's office.
