Didier Dubreucq — nicknamed “Blue Eyes” — has been authorised to travel only for medical appointments, his lawyers Dominique Ousset and Victoria Anfuso, without disclosing the 62-year-old’s condition.
A career gangster who had already been convicted of robbery and drug trafficking, Dubreucq is suspected of being part of the five-man team that robbed Kardashian of a ring and other jewels worth millions in October 2016.
Kardashian was staying in a luxury residence during Paris Fashion Week when she was held up by men who threatened her with a gun before tying her up, gagging her and locking her in a bathroom.
The men made off in the middle of the night with a haul worth an estimated nine million euros ($10.6 million).
Six people are being held in connection with the case.
