A pre-dawn stoush allegedly involving a gun-toting motorist following a crash in Auckland has ended in the arrest of a man and a woman.
Police say they received word of an altercation between the occupants of two cars on William Denny Ave in Westmere about 5.45am on Saturday.
A photographer at the scene captured officers near a damaged Subaru Outback, but the circumstances of the crash remain unclear.
A police statement said one of the occupants was reported to be in possession of a firearm, but no arrests were made at the scene.
Then about 2.30pm on the Southern Motorway police saw a "vehicle of interest" linked to the incident.
