French authorities have arrested five additional suspects in connection with the October 19 jewel heist at the Louvre Museum, bringing the total number of people detained in the case to seven, Paris Prosecutor Laure Beccuau announced Wednesday.

The latest arrests took place in Seine-Saint-Denis, a suburb north of Paris long known as a hub for organized crime networks. Authorities have not yet released the names of the suspects.

Speaking on RTL radio, Beccuau confirmed that while the stolen royal jewelry—valued at roughly €88 million ($100 million)—has not yet been recovered, forensic evidence played a crucial role in identifying new suspects.

“One of the men arrested yesterday is considered a major person of interest,” Beccuau said, noting that his DNA was found at the scene of the crime.

According to French police sources who spoke to News men, one suspect had already been under surveillance for several days before being taken into custody during the coordinated raids.

The arrests follow last weekend’s detention of two men in their 30s, both residents of Seine-Saint-Denis, who were apprehended after police matched DNA traces found on a helmet left behind at the museum to one of the suspects.

Investigators said that man was then placed under phone and physical surveillance, which ultimately led police to his associates.

One of the suspects was arrested Saturday night at Charles de Gaulle Airport while allegedly attempting to board a flight to Algeria, police said. Another, a dual citizen of France and Mali, was detained earlier this week, though officials later clarified he had no immediate plans to leave the country.

Both men are known to law enforcement for prior burglary offenses, according to investigators.

Authorities continue to probe whether the daring seven-minute heist, which saw thieves use a mechanized lift to smash through an upper-level window of the Louvre and escape with priceless jewels, may have involved inside assistance.

“We are not excluding the possibility that someone within the museum provided logistical or security information,” a police source said.

The Louvre Museum, which reopened days after the robbery, remains under heightened security as the hunt for the missing jewels—including pieces belonging to France’s historic crown collection—continues.

Beccuau said the investigation is “progressing rapidly” and vowed that authorities “will pursue every lead until the treasures of the French people are recovered.”
