At the Paris trial of 10 people accused of robbing Kim Kardashian at gunpoint in 2016, a defendant who wrote a book about the jewellery heist Tuesday said he regretted participating while one of his co-accused vehemently denied any involvement. Since becoming a father at the age of 50, Didier said he put an end to the “big mistakes” he committed in the past and denied being involved in robbing Kardashian.
