The suspect in the murder of two homeless people, found dead on Wednesday, was arrested on Sunday in the center of Nice and was injured by the police after pulling out at least one bladed weapon, we learned from police and municipal sources.
This 48-year-old man, of Iranian nationality and known for acts of common law, according to a police source, had been wanted for several days, said on the spot the first deputy mayor of Nice, Anthony Borré.
Spotted by a crew of three police officers, he fled before returning to a policewoman who was pursuing him, pulling out a machete and a knife, a police source reported.
She then shot and hit him in the shoulder, before he was arrested, she added.
He was transferred to the hospital, according to the deputy mayor.
On Wednesday, two bodies were found near a squatted house on the heights of Nice.
