French police detain man and seize guns after five people shot dead near Dunkirk

French police are investigating the deaths of five people who were fatally shot in the Dunkirk area of northern France on Saturday.

A 22-year-old man later turned himself in to police, according to authorities and local media.

An unnamed company owner in Wormhout, located south of Dunkirk, was killed first, followed by two private security agents and two migrants in Loon-Plage, just west of Dunkirk, according to the Interior Ministry.

Dunkirk’s prosecutor said the suspect gave himself up to the police in Ghyvelde, east of Dunkirk, at about 5.20pm and said he had killed five people.

The man, who was unknown to authorities, was taken into police custody, according to the prosecutor, who said several firearms were found in the man’s car.

Officials are trying to determine the suspect’s motive.
