Police officials said the arrests took place in a coordinated strike early Monday morning in several locations in the Paris region. The suspects — 14 men and three women — range in age from 23 to 72. Some of them have ties to organized crime. One of the men arrested, Michael Madar, was her driver that night. Madar's younger brother Gary is also one of the suspects arrested, the Chicago Tribune reports.
The suspects have not yet been charged, and police can hold them for up to 96 hours before they're forced to let them go.
Jean Veil, Kardashian's attorney in France, said the news of arrests is "a great satisfaction."
"These arrests are a nice surprise because we might be able to find the jewels," he told the French magazine L'Express on Monday.
On Oct. 3 of last year, masked gunmen broke into the apartment where Kardashian was staying, bound and gagged her and put her in the bathtub, and stole about $11 million dollars worth of jewelry from the reality TV star.
Kardashian addressed the robbery publicly for the first time in a teaser for Keeping Up With the Kardashians last week, recalling the fear she felt in that moment during a conversation with her sisters. "They're going to shoot me in the back," she says. "There's no way out. It makes me so upset to think about it."
