Northern Territory Police are investigating the circumstances of a single vehicle crash near Larrimah on Monday evening, in which two people died.

The man and woman, aged 74 and 67, were discovered by a passing motorist approximately 10km south of Larrimah.

Members from Mataranka and Maranboy attended the scene, with traffic diversions in place overnight while detectives from the Major Crash Investigation Unit travelled from Darwin to commence investigations.

Detective Senior Sergeant Corey Borton said, “This is a tragic way to end a long weekend, and while we are still investigating the causes of this crash, we’d just remind all road users to take extra care, slow down and take a break if you are travelling long distances.”
