Earlier, a woman with a Vietnamese passport was arrested in this case. It is speculated that North Korean authorities are behind the assassination of the estranged half brother of North Korea's leader Kim Jong Un. Kim Jong Nam started to fall out of grace with his father, the late Kim Jong Il, in 2001 when the former tried to enter Japan on a fake passport to visit Disneyland. In the following decade more issues between father and son occurred. It was reported in media that Kim Jong Nam had been targeted for assassination in the past.

It is interesting to note that Kim Jong Un never met his murdered half-brother. In North Korea children who have a chance of succeeding their father on the throne are raised separately.
