Some parents had an argument with their teenage son, and he went off in a huff taking the family car (technically without asking permission). His parents thought to themselves "I know, we'll teach him a lesson", so they reported the car stolen. They intended to later on drop the charges (which would have royally peeved the police, making a false charge is also a crime).
Anyway, the cops caught the kid, and because Grand Theft Auto (or whatever the NZ equivalent is) is rated as amongst the most serious crimes, he got sent off (before formal charges were laid) to a maximum security facility in the back of a paddy wagon.
He didn't even make it to the maximum security facility. One of the other prisoners being transported there in the same van killed him.
* it wasn't recent (2006)
* he was sent to prison because his parents denied bail, not because GTA is some heinous crime in NZ
