Eight people were found guilty by a court in Paris on Friday in connection with a brazen robbery against Kim Kardashian nearly a decade ago.

Ms. Kardashian, 44, a reality TV star and entrepreneur, was gagged, bound with zip ties and robbed at gunpoint of jewelry worth millions of dollars at a luxury residence she had rented during Paris Fashion Week in October 2016.

Seven men and one woman were found guilty on charges ranging from direct involvement in the robbery to lesser complicity in it. The court sentenced them to three to eight years in prison, with the sentences mostly or entirely suspended.

“The sentences are fairly lenient,” David De Pas, the presiding judge, acknowledged as he read out the ruling, citing the advanced age and health issues of many of the defendants as one of the main reasons.

Even so, he added: “You did harm.”

The court found a ninth defendant guilty of illegally acquiring and possessing firearms but cleared him of involvement in the robbery. It acquitted a 10th defendant entirely on the grounds that there was not enough evidence against him for a conviction.

Reporters had nicknamed the main suspects in the case the “grandpa robbers” — a group of grizzled criminals, most of whom are now in their 60s and 70s, who were accused of staging one of the most daring celebrity heists in France’s recent history.
