The trial over the Paris robbery that saw Kim Kardashian's multi-million dollar engagement ring stolen has kicked off.

Almost nine years after Kim Kardashian was held at gunpoint and robbed of more than $9 million in jewelry in Paris, the suspects are now on trial.

A group of men dubbed the "grandpa gang" were among ten suspects who went on trial on Monday on charges of robbing reality TV star Kim Kardashian at gunpoint and stealing jewelry worth millions of dollars during Paris Fashion Week nearly a decade ago.
