NT police are applying for the extradition of a man from north Queensland in relation to the death of a man who died after an assault in Darwin last month.

A man has been arrested in Queensland in relation to the assault and death of a 68-year-old man in Darwin last month.

Northern Territory detectives have travelled to Queensland to apply for the 23-year-old’s extradition.

It’s alleged the older man was walking along Darwin’s main entertainment strip at about 2am on August 9 when he got into an altercation with the younger man.

He was struck and hit his head as he fell to the ground, and died in hospital as a result of his injuries two weeks later on August 22.
